PRELIMINARY — SUBJECT TO COMPLETION — DATED NOVEMBER 20, 2014

MERGER PROPOSAL — YOUR VOTE IS VERY IMPORTANT

The board of directors of Wesbanco, Inc., or WesBanco, and the board of directors of ESB Financial Corporation, or ESB, have agreed to a strategic combination of the two companies under the terms of the Agreement and Plan of Merger, dated October 29, 2014, and referred to in this document as the merger agreement by and between WesBanco, Wesbanco Bank, Inc., ESB and ESB Bank. At the effective time of the merger, ESB will merge with and into WesBanco with WesBanco continuing as the surviving corporation.

If the merger contemplated by the merger agreement is completed, each share of common stock of ESB outstanding immediately prior to the effective time of the merger, will be converted into the right to receive (1) 0.502 of a share of common stock of WesBanco and (2) $1.76 in cash, without interest. WesBanco shares will be unaffected by the merger and the merger will be tax-free to WesBanco shareholders. Shareholders of ESB generally will not recognize any gain or loss upon receipt of shares of WesBanco common stock in exchange for ESB common stock in the merger, but will recognize gain (but not loss) in an amount not to exceed any cash received as part of the merger consideration (except with respect to any cash received in lieu of fractional shares).

At the WesBanco special meeting, WesBanco shareholders will be asked to consider the following matters: (i) approval of the issuance of shares of WesBanco common stock, par value $2.0833 per share, in connection with the merger contemplated by the merger agreement; (2) approval of the adjournment of the WesBanco special meeting if necessary to solicit additional proxies in favor of the approval of the issuance of shares of WesBanco common stock in connection with the merger; and (3) any other business properly presented at the meeting, or any adjournments thereof.

At the ESB special meeting, ESB shareholders will be asked to consider the following matters: (1) adoption of the merger agreement; (2) approval, in a non-binding advisory vote, of the compensation payable to the named executive officers of ESB in connection with the merger; (3) approval of the adjournment of the ESB special meeting if necessary to solicit additional proxies in favor of the adoption of the merger agreement; and (4) any other business properly presented at the meeting, or any adjournments thereof.

The number of shares of WesBanco common stock that ESB shareholders will receive for the stock portion of the merger consideration is fixed, and the market value of those shares will fluctuate with the market price of WesBanco common stock and will not be known at the time ESB shareholders vote on the merger agreement. Based on the closing price of WesBanco’s common stock of $34.74 on the NASDAQ Global Select Market, or NASDAQ, on October 29, 2014, the last full trading day immediately prior to the public announcement of the merger agreement, the value of the per share merger consideration payable to ESB shareholders was $19.20. Based on the closing price of WesBanco’s common stock of $[—] on NASDAQ on [—], 2014, the last full trading day before the date of this joint proxy statement/prospectus, the value of the per share merger consideration payable to ESB shareholders was $[—]. We urge you to obtain current market quotations for WesBanco common stock (NASDAQ: trading symbol “WSBC”) and ESB common stock (NASDAQ: trading symbol “ESBF”). Based on the number of (1) restricted and unrestricted shares of ESB common stock outstanding and (2) shares of ESB common stock potentially issuable pursuant to outstanding stock options that are vested or that are expected to vest prior to completion of the merger, the maximum number of shares of WesBanco common stock issuable in the merger is expected to be approximately 9,483,966.

Your vote is very important. Whether or not you plan to attend your shareholders’ meeting, please take the time to vote by completing and mailing the enclosed proxy card in accordance with the instructions on the proxy card. WesBanco shareholders may also cast their votes over the Internet or by telephone in accordance with the instructions on the WesBanco proxy card. We cannot complete the merger unless ESB shareholders adopt the merger agreement and WesBanco shareholders approve the issuance of shares of WesBanco common stock in connection with the merger. Based on the reasons for the merger described in the accompanying document, each of our boards of directors believes that the merger is advisable and in the best interest of WesBanco and ESB.

This document provides you with detailed information about these meetings and the proposed merger. You also can obtain information about our companies from publicly available documents filed with the Securities and Exchange Commission. We encourage you to carefully and thoughtfully read this entire document, including all its annexes, and we especially encourage you to read the section entitled “Risk Factors” beginning on page 32.

The WesBanco board of directors unanimously recommends that WesBanco shareholders vote “FOR” the approval of the issuance of shares of WesBanco common stock in connection with the merger and “FOR” the adjournment of the WesBanco special meeting, if necessary, to solicit additional proxies in favor of the approval of the issuance of shares of WesBanco common stock in connection with the merger. The ESB board of directors unanimously recommends that ESB shareholders vote “FOR” the adoption of the merger agreement, “FOR” the approval, on a non-binding, advisory basis, of the compensation payable to the named executive officers of ESB in connection with the merger and “FOR” the adjournment of the ESB special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to adopt the merger agreement.

We strongly support this combination of our companies and look forward to the successful completion of the merger.

Because the number of shares of WesBanco common stock that ESB shareholders will receive for the stock portion of the merger consideration is fixed, the implied value of the stock portion of the merger consideration will fluctuate as the market price of WesBanco common stock fluctuates. As a result, the value of the merger consideration that ESB shareholders will receive upon completion of the merger could be greater than, less than or the same as the value of the merger consideration on the date of this joint proxy statement/prospectus or at the time of the WesBanco or ESB special meetings. ESB shareholders should obtain current stock price quotations for WesBanco common stock and ESB common stock before deciding how to vote with respect to the adoption of the merger agreement. WesBanco common stock is listed for trading on the Nasdaq Global Select Market under the symbol “WSBC.” ESB common stock is listed for trading on the Nasdaq Global Select Market under the symbol “ESBF.”

Q: What do the WesBanco and ESB boards of directors recommend?

A: WesBanco. The WesBanco board of directors has unanimously determined that the merger is in the best interests of WesBanco and WesBanco’s shareholders and unanimously recommends that WesBanco shareholders vote FOR approval of the issuance of shares of WesBanco common stock in connection with the merger and FOR approval of the adjournment proposal.

In making this determination, WesBanco’s board of directors considered the factors described under “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — WesBanco’s Reasons for the Merger.”

ESB. The ESB board of directors has unanimously determined that the merger is in the best interests of ESB and ESB’s shareholders and unanimously recommends that ESB shareholders vote FOR adoption of the merger agreement; FOR approval, in a non-binding advisory vote, of the compensation payable to the named executive officers of ESB in connection with the merger and FOR approval of the adjournment proposal.

In making this determination, ESB’s board of directors considered the factors described under “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — ESB’s Reasons for the Merger.”

Q: How do I vote my shares in the ESB Employee Stock Ownership Plan or the ESB Retirement Savings Plan?

A: If you are a participant in the ESB Employee Stock Ownership Plan (the “ESOP”) or the ESB Retirement Savings Plan (the “401(k) Plan”), you will receive a voting instruction form for each plan that reflects all shares you may vote under the plan. Under the terms of the plans, all shares held by the plans are voted by the respective trustees, but each participant may direct the trustees on how to vote the shares of ESB common stock allocated to his or her account in the plans. Allocated shares in the ESOP for which no timely voting instructions are received will be voted by the ESOP trustees in the same ratio as to those shares for which ESOP participant’s instructions are received. If your voting instructions for the 401(k) Plan are not received, the shares allocated to your account will not be voted. The deadline for returning your voting instruction forms to the plan trustees is [—], 20[—].

Q: When do you expect to complete the merger?

A: We anticipate that it is more probable than not we will obtain all necessary regulatory approvals, and be able to consummate the merger, in the first or second quarter of 2015. However, we cannot assure you when or if the merger will occur. We must first obtain the requisite approval of WesBanco and ESB shareholders at their respective special meetings and WesBanco and ESB must obtain the requisite regulatory approvals to complete the merger.

Q: What happens if the merger is not completed?

A: If the merger is not completed, holders of ESB common stock will not receive any consideration for their shares in connection with the merger. Instead, ESB will remain an independent public company and its common stock will continue to be listed and traded on the Nasdaq Global Select Market.

Q: Why are ESB shareholders being asked to consider and vote upon a proposal to approve, in a non-binding advisory vote, the compensation payable to the named executive officers of ESB in connection with the merger?

A: Under Securities and Exchange Commission rules, ESB is required to seek a non-binding, advisory vote with respect to the compensation payable to ESB’s named executive officers in connection with the merger, or “golden parachute” compensation.

Q: What will happen if ESB shareholders do not approve the golden parachute compensation?

A: Approval of the compensation payable to ESB’s named executive officers in connection with the merger is not a condition to completion of the merger. The vote is an advisory vote and will not be binding on ESB. Therefore, if the merger agreement is adopted by ESB shareholders and the issuance of shares of WesBanco common stock in connection with the merger is approved by WesBanco shareholders and the merger is completed, this compensation, including amounts that ESB is contractually obligated to pay, could still be payable regardless of the outcome of the advisory vote, subject to the conditions applicable thereto.

Q: What vote of WesBanco shareholders is required to approve each proposal?

A: To be approved, WesBanco proposals 1 and 2 require the affirmative vote of at least a majority of the outstanding shares of WesBanco common stock.

As of the WesBanco record date, there were [—] shares of WesBanco common stock outstanding and entitled to vote at the WesBanco special meeting, held by approximately [—] holders of record. As of the WesBanco record date, the directors and executive officers of WesBanco controlled approximately [—]% of the outstanding shares of WesBanco common stock entitled to vote at the special meeting.

- 3 -

Q: What vote of ESB shareholders is required to approve each proposal?

A: To be approved, ESB proposals 1, 2 and 3 require the affirmative vote of a majority of the votes cast by the holders of ESB common stock entitled to vote thereon at the ESB shareholders’ meeting at which a quorum is present.

As of the ESB record date, there were [—] shares of ESB common stock outstanding and entitled to vote at the ESB special meeting, held by approximately [—] holders of record. As of the ESB record date, the directors and executive officers of ESB controlled approximately [—]% of the outstanding shares of ESB common stock entitled to vote at the special meeting. In addition, certain officers and directors of ESB have entered into voting agreements with WesBanco wherein the officer or director has agreed to vote their ESB shares in favor of adoption of the merger agreement.

Q: How do I vote?

A: WesBanco shareholders. If you are a shareholder of record of WesBanco as of the WesBanco record date, you may vote in person by attending the WesBanco special meeting or, to ensure your shares are represented at the WesBanco special meeting, you may vote by:

• accessing the Internet website specified on your proxy card;

• calling the toll-free number specified on your proxy card; or

• signing and returning the enclosed proxy card in the postage-paid envelope provided.

ESB shareholders. If you are a shareholder of record of ESB as of the ESB record date, you may vote in person by attending the ESB special meeting or by signing and returning the enclosed proxy card in the postage-paid envelope provided.

If you hold your WesBanco or ESB shares in the name of a bank or broker, please see the discussion below.

Q: What is a quorum?

A: In order for business to be conducted at the WesBanco special meeting or the ESB special meeting, a quorum must be present. The quorum requirement for holding the WesBanco and ESB special meetings and transacting business at the WesBanco and ESB special meetings is a majority of the outstanding shares of WesBanco common stock or ESB common stock, as the case may be, as of the applicable record date that are present or represented at the respective WesBanco and ESB special meetings. The shares may be present in person or represented by proxy at the WesBanco and ESB special meetings. Proxies received but marked as abstentions and broker non-votes are considered to be present and entitled to vote at the meeting for the purposes of determining a quorum.

Q: Your shares are held in your broker’s name (also known as “street name”). How do you vote those shares?

A: Copies of this joint proxy statement/prospectus were sent to you by your broker. The broker will request instructions from you as to how you want your shares to be voted, and the broker will vote your shares according to your instructions.

Q: If your shares are held in “street name” by a broker, won’t your broker vote those shares for you?

A: Not unless you provide your broker with instructions on how to vote your “street name” shares. Broker non-votes may occur because certain beneficial holders of shares of WesBanco common stock or ESB common stock hold their shares in “street name” through a broker, bank or other nominee. Under the rules of the New York Stock Exchange which governs brokers, brokers, banks and other nominees are not permitted to exercise voting discretion on any of the proposals to be voted upon at the WesBanco special meeting or the ESB special meeting. Therefore, if a beneficial holder of shares of WesBanco common stock or ESB

- 4 -

common stock does not give the broker, bank or other nominee specific voting instructions, the holder’s shares of common stock will not be voted on those proposals and a broker non-vote will occur. You should therefore be sure to provide your broker with instructions on how to vote your shares.

Abstentions, if any, and broker non-votes, if any, are counted as present for the purpose of determining whether a quorum is present. Once a quorum for the WesBanco special meeting is established, abstentions and broker non-votes will have the effect of a vote “Against” all of the proposals to be voted on at the WesBanco special meeting. Once a quorum for the ESB special meeting is established, abstentions and broker non-votes will have no effect on any of the proposals to be voted on at the ESB special meeting.

Please check the voting form used by your broker to see if it offers telephone or Internet submission of proxies.

Q: What happens if you return your proxy card without indicating how to vote?

A: If you return your signed proxy card without indicating how to vote on any particular proposal, the WesBanco or ESB stock represented by your proxy will be voted on each proposal presented at the WesBanco special meeting or ESB special meeting, as the case may be, in accordance with the applicable board’s recommendation on that proposal. In that case, if you are a WesBanco shareholder, your shares of WesBanco common stock will be voted “FOR” approval of the issuance of shares of WesBanco common stock in connection with the merger; and “FOR” the adjournment of the WesBanco special meeting, if necessary, to solicit additional proxies in favor of the approval of the issuance of shares of WesBanco common stock in connection with the merger. If you are an ESB shareholder and you return a signed proxy card without indicating how to vote on any particular proposal, your shares of ESB common stock will be voted “FOR” adoption of the merger agreement; “FOR” approval, in a non-binding advisory vote, of the compensation payable to the named executive officers of ESB in connection with the merger; and “FOR” the adjournment of the ESB special meeting, if necessary, to solicit additional proxies in favor of the adoption of the merger agreement.

Q: Can you change your vote after you have delivered your proxy card?

A: Yes. You may change your vote at any time before your proxy is voted at your meeting. You can do this in any of the three following ways:

• by sending a written notice to the corporate secretary of WesBanco or ESB, as the case may be, in time to be received before the applicable WesBanco or ESB special meeting stating that you would like to revoke your proxy;

• by completing, signing and dating another proxy card bearing a later date and returning it by mail in time to be received before the WesBanco or ESB special meeting, as the case may be, or, if you are a WesBanco shareholder, you can change your vote by submitting a new, valid proxy by proxy card, Internet or telephone, with a later date, in which case your later submitted proxy will be recorded and your earlier proxy revoked; or

• if you are a holder of record, by attending the applicable WesBanco or ESB special meeting and voting in person.

If your shares are held in an account at a broker or bank, you should contact your broker or bank to change your vote.

Q: Will shareholders have dissenters’ or appraisal rights?

A: No. If you are a WesBanco shareholder who objects to the merger, you may vote against approval of the issuance of shares of WesBanco common stock in connection with the merger. If you are an ESB shareholder who objects to the merger, you may vote against adoption of the merger agreement. However, under applicable West Virginia law, WesBanco shareholders will not be entitled to appraisal rights. Similarly, under Pennsylvania law, holders of ESB common stock will not be entitled to dissenters’ rights.

Q: What do you need to do now?

A: After you carefully read and consider the information contained in and incorporated by reference into this document, please respond as soon as possible by completing, signing and dating your proxy card and returning it in the enclosed postage-paid return envelope, or, if you are a WesBanco shareholder, you may also submit your proxy or voting instructions by telephone or through the Internet, so that your shares will be represented and voted at the applicable WesBanco or ESB special meeting. This will not prevent you from attending the WesBanco special meeting or ESB special meeting, as applicable, and voting in person; however in order to assist us in tabulating the votes at the applicable special meeting, we encourage you to vote by proxy even if you do plan to attend the applicable special meeting in person.

Q: Should you send in your ESB stock certificates now?

A: No. You should not send in your ESB stock certificates until you receive transmittal materials.

Q: Who will solicit and pay the cost of soliciting proxies?

A: WesBanco has engaged a professional proxy solicitation firm, Georgeson Inc. (“Georgeson”), to assist in soliciting proxies for use at the WesBanco special meeting. Similarly, ESB has engaged a professional proxy solicitation firm, Morrow & Co., LLC (“Morrow”), to assist in soliciting proxies for use at the ESB special meeting. Under the terms of the merger agreement, WesBanco has agreed to pay the fees and expenses of both Georgeson and Morrow. WesBanco will pay Georgeson a fee of $9,000 and will reimburse Georgeson for its out-of-pocket expenses. Morrow will be paid a fee of $6,000 and will be reimbursed for its out-of-pocket expenses.

Each of WesBanco and ESB may also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of shares of WesBanco and ESB common stock for their expenses in forwarding soliciting materials to beneficial owners of the WesBanco and ESB common stock and in obtaining voting instructions from those owners. In addition, the WesBanco and ESB directors, officers and employees may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies but may be reimbursed for their reasonable out-of-pocket expenses that they incur.

SUMMARY

This summary highlights selected information from this joint proxy statement/prospectus and may not contain all of the information that is important to you. The merger agreement is attached to this joint proxy statement/prospectus as Annex A. To fully understand the merger and for a more complete description of the terms of the merger and the merger agreement, you should carefully read this entire document, including the annexes, and the documents we refer you to under the caption “Where You Can Find More Information About WesBanco and ESB” beginning on page [—]. This joint proxy statement/prospectus, including information included or incorporated by reference in this joint proxy statement/prospectus, contains a number of forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 regarding the financial condition, results of operations, earnings outlook, business and prospects of WesBanco and ESB, and the potential combined company, as well as statements applicable to the period following the completion of the merger. You can find some of these statements by looking for words such as “plan,” “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project,” “potential,” “possible” or other similar expressions. These forward-looking statements involve certain risks and uncertainties. The ability of either WesBanco or ESB to predict results or the actual effects of our plans and strategies, particularly after the merger, is inherently uncertain. Because these forward-looking statements are subject to assumptions and uncertainties, actual results may differ materially from those expressed in or implied by these forward-looking statements. See “Cautionary Statement Regarding Forward-Looking Statements” on page [—].

What ESB Shareholders Will Receive in the Merger (See page [—])

If the merger is completed, for each share of ESB common stock that you own you will receive, (i) 0.502 of a share of WesBanco common stock and (ii) $1.76 in cash, without interest, subject to possible adjustment in accordance with the terms of the merger agreement as discussed below. Collectively, we refer to the 0.502 of a share of WesBanco common stock and the $1.76 in cash to be received as the “merger consideration.” Instead of fractional shares of WesBanco, ESB shareholders will receive a check for any fractional shares based on the average closing price of WesBanco common stock during a specified period before the effective time of the merger.

The 0.502 exchange ratio is subject to adjustment if certain termination provisions, based on the market price of WesBanco’s common stock, have been triggered and the ESB board of directors elects to terminate the merger agreement. ESB will have a right to terminate the merger agreement if the average closing price of WesBanco common stock during a specified period before the effective time of the merger is less than $27.98 per share and WesBanco common stock underperforms an index of financial institution stocks by more than 15%. However, ESB would not have the right to terminate the merger agreement if WesBanco were to elect to make a compensating adjustment in the exchange ratio. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Termination of the Merger Agreement” beginning on page [—]. The exchange ratio is also subject to adjustment if WesBanco completes certain corporate transactions, such as a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other like changes in WesBanco’s capitalization.

Opinions of Financial Advisors (See page [—])

WesBanco. On October 29, 2014, FBR Capital Markets & Co. (which we refer to as “FBRC”) rendered its oral opinion to the WesBanco board of directors (which was subsequently confirmed in writing by delivery of FBRC’s written opinion addressed to the WesBanco board of directors dated the same date), to the effect that, as of October 29, 2014, the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement was fair, from a financial point of view, to WesBanco.

FBRC’s opinion was directed to the WesBanco board of directors (in its capacity as such), and only addressed the fairness, from a financial point of view, to WesBanco of the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement and did not address any other aspect or implication of the transaction. In addition, FBRC’s opinion only addressed the fairness as of the date of the opinion. Although subsequent developments could affect its opinion, FBRC does not have any obligation to update, revise or reaffirm its opinion.

In the portions of this joint proxy statement/prospectus describing FBRC’s analyses and opinion, the merger and the bank merger are referred to collectively as the “transaction.”

The cash payment will be subject to applicable tax withholding.

Similarly, a quorum at the ESB special meeting requires the presence, whether in person or by proxy, of a majority of the outstanding shares of ESB common stock as of the ESB record date.

Shares held in street name by brokers and other record holders but not voted at the applicable special meeting because such brokers have not received voting instructions from the underlying owners are called broker non-votes. An abstention occurs when a shareholder attends a meeting, either in person or by proxy, but abstains from voting.

WesBanco. At the WesBanco special meeting, abstentions and broker non-votes will be counted in determining whether a quorum is present. However, abstentions, broker non-votes and a complete failure to vote will have the same effect as a vote “Against” all of the proposals being voted on by WesBanco shareholders. If no instruction as to how to vote is given (including no instruction to abstain) in an executed, duly returned and not revoked proxy, the proxy will be voted “For” (i) approval of the issuance of shares of WesBanco common stock in connection with the merger; and (ii) adjournment of the WesBanco special meeting if necessary to solicit additional proxies in favor of the approval of the issuance of shares of WesBanco common stock in connection with the merger.

ESB. At the ESB special meeting, abstentions and broker non-votes will be counted in determining whether a quorum is present. However, abstentions, broker non-votes and a complete failure to vote will have no effect on the outcome of any of the proposals being voted on by ESB shareholders. If no instruction as to how to vote is given (including no instruction to abstain) in an executed, duly returned and not revoked proxy, the proxy will be voted “For” (i) adoption of the merger agreement, (ii) approval, in a non-binding advisory vote, of the compensation payable to the named executive officers of ESB in connection with the merger; and (iii) approval of the adjournment of the ESB special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to adopt the merger agreement at the time of the ESB special meeting.

No Dissenters’ or Appraisal Rights (See page [—])

Under applicable West Virginia and Pennsylvania law, holders of WesBanco or ESB common stock will not be entitled to dissenters’ or appraisal rights. Therefore, if you own shares of WesBanco common stock on the WesBanco record date but you are against the merger, you may vote against approval of the issuance of shares of WesBanco common stock in connection with the merger but you may not exercise dissenters’ or appraisal rights. Similarly, if you own shares of ESB common stock on the ESB record date but you are against the merger, you may vote against adoption of the merger agreement but you may not exercise dissenters’ or appraisal rights for your ESB shares.

Shares to be Issued by WesBanco in the Merger; Ownership of WesBanco after the Merger (See page [—])

WesBanco will issue a maximum of approximately 9,483,966 shares of its common stock to ESB shareholders in connection with the merger, based on the number of (1) restricted and unrestricted shares of ESB common stock outstanding on the ESB record date and (2) shares of ESB common stock potentially issuable pursuant to outstanding stock options that are vested or that are expected to vest prior to completion of the merger, assuming no adjustment to the exchange ratio is made. Assuming that WesBanco issues that maximum number of shares, it would constitute approximately 24.5% of the outstanding stock of WesBanco after the merger, based on the number of shares of WesBanco common stock outstanding on September 30, 2014. The WesBanco shares to be issued in the merger will be listed for trading on the Nasdaq Global Select Market under the symbol “WSBC.”

Material U.S. Federal Income Tax Consequences (See page [—])

It is a condition to the completion of the merger, unless waived by the parties in writing, that each of WesBanco and ESB receives a legal opinion from their respective tax counsel to the effect that the merger will be treated as a “reorganization” for United States federal income tax purposes within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). Accordingly, we expect the merger generally to be tax-free to ESB shareholders for United States federal income tax purposes with respect to the shares of WesBanco common stock that they receive pursuant to the merger. An ESB shareholder generally will recognize gain, but not loss, in an amount equal to the lesser of (1) the amount of gain realized (i.e., the excess, if any, of the sum of the cash received and the fair market value of the WesBanco common stock received pursuant to the merger over that holder’s adjusted tax basis in its shares of ESB common stock surrendered) and (2) the amount of cash received pursuant to the merger. In addition, ESB shareholders will recognize gain or loss with respect to the receipt of cash in lieu of fractional shares.

You should read the summary under the caption “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Material Federal Income Tax Consequences of the Merger” beginning on page [—] for a more complete discussion of the federal income tax consequences of the merger. You should also consult your own tax advisor concerning all federal, state, local and foreign tax consequences of the merger that may apply to you.

Certain Differences in the Rights of Shareholders (See page [—])

ESB is a Pennsylvania corporation governed by Pennsylvania law and WesBanco is a West Virginia corporation governed by West Virginia law. Once the merger occurs, ESB shareholders will become shareholders of WesBanco and their rights will be governed by West Virginia law and WesBanco’s corporate governing documents rather than Pennsylvania law and ESB’s governing documents. Because of the differences between the laws of the Commonwealth of Pennsylvania and the State of West Virginia and the respective corporate governing documents of ESB and WesBanco, ESB’s shareholders’ rights as shareholders will change

- 12 -

as a result of the merger. These include, among others, differences in shareholders’ rights related to notice and adjournment of shareholder meetings, the calling of special meetings of shareholders, dissenters’ rights, the number and term of directors, nomination of directors, removal of directors and filling vacancies on the board of directors, cumulative voting, indemnification of officers and directors, amendment of articles of incorporation and bylaws, and statutory provisions affecting control share acquisitions and business combinations.

Conditions to the Merger (See page [—])

Completion of the merger is subject to the satisfaction or waiver of the conditions specified in the merger agreement, including, among others, those listed below:

• the adoption of the merger agreement by the shareholders of ESB;

• approval of the issuance of shares of WesBanco common stock in connection with the merger by WesBanco shareholders;

• the absence of a law or injunction prohibiting the merger;

• receipt by WesBanco and ESB of all necessary approvals of governmental and regulatory authorities;

• the receipt of an opinion from each party’s tax counsel, dated as of the closing date of the merger, to the effect that for federal income tax purposes the merger will be treated as a reorganization within the meaning of Section 368(a) of the Code; and

• the shares of WesBanco common stock to be issued in exchange for the shares of ESB common stock shall have been approved for listing on the Nasdaq Global Select Market.

Termination of the Merger Agreement (See page [—])

The parties can agree to terminate the merger agreement at any time prior to completion of the merger, and either WesBanco or ESB can terminate the merger agreement if, among other reasons, any of the following occurs:

• the merger agreement is not adopted by the ESB shareholders;

• the issuance of shares of WesBanco common stock in connection with the merger is not approved by WesBanco shareholders;

• the merger is not completed by July 31, 2015;

• a court or other governmental authority permanently prohibits the merger; or

• the other party breaches or materially fails to comply with any of its representations or warranties or obligations under the merger agreement.

ESB will also have the right to terminate the merger agreement if the average closing price of WesBanco common stock during a specified period before the effective time of the merger is less than $27.98 and WesBanco common stock underperforms the Nasdaq Bank Index by more than 15%, unless WesBanco were to elect to make a compensating adjustment to the exchange ratio. Subject to certain conditions, ESB may also terminate the merger agreement in order to enter into an agreement with respect to an unsolicited proposal that if consummated would be reasonably likely to result in a transaction more favorable to ESB’s shareholders from a financial point of view, provided that ESB pays the termination fee described below upon entering into such agreement.

Termination Fee (See page [—])

The merger agreement provides that if the merger agreement is terminated under certain circumstances, described more fully beginning on page [—], ESB will be required to pay a termination fee of $11,354,000 to WesBanco.

- 13 -

We May Amend the Terms of the Merger and Waive Rights Under the Merger Agreement (See page [—])

We may jointly amend the terms of the merger agreement, and either party may waive its right to require the other party to adhere to any of those terms, to the extent legally permissible. However, after the approval of the merger agreement by the ESB shareholders, there may not be, without further approval of ESB’s shareholders, any amendment of the merger agreement that requires such further approval under applicable law or would alter the amount or kind of the WesBanco common stock portion of the merger consideration to be received by ESB shareholders.

Effective Date of the Merger (See page [—])

We expect the merger to be completed as soon as practicable after all regulatory approvals and shareholder approvals have been received. We expect this to occur during the first or second quarter of 2015.

Regulatory Approvals (See page [—])

In addition to the approvals of the WesBanco and ESB shareholders, the merger is subject to the approval of the Federal Deposit Insurance Corporation, Board of Governors of the Federal Reserve System (unless a waiver is granted), the West Virginia Division of Financial Institutions and the Pennsylvania Department of Banking. These governmental authorities may impose conditions for granting approval of the merger. Neither WesBanco nor ESB can offer any assurance that all necessary approvals will be obtained or the date when any such approvals will be obtained.

Interests of Certain Persons in the Merger (See page [—])

The directors and executive officers of ESB have financial and other interests in the merger that differ from, or are in addition to, their interests as shareholders of ESB. These interests include, but are not limited to:

• the continued indemnification of current and former directors and executive officers under the merger agreement and providing these individuals with directors’ and officers’ insurance for six years after the merger;

• the receipt of payments by the executive officers of ESB and certain other officers of ESB Bank pursuant to employment or change in control severance agreements with ESB and ESB Bank;

• the continuation of certain benefits for certain officers and directors of ESB;

• the accelerated vesting upon completion of the merger of all outstanding stock options and restricted stock awards which remain unvested immediately prior to completion of the merger;

• the receipt of cash payments upon completion of the merger as a result of cancellation of all outstanding stock options, whether or not then exercisable;

• the appointment of Charlotte A Zuschlag, ESB’s President and Chief Executive Officer, and Ronald W. Owen, a director of ESB Bank, to the board of directors of WesBanco upon completion of the merger;

• concurrently with the execution of the merger agreement, WesBanco and ESB entered into a separation agreement and a non-competition agreement with each of Charlotte A. Zuschlag, Charles P. Evanoski, Frank D. Martz and Todd F. Palkovich, pursuant to which such executive officers will receive lump sum payments upon completion of the merger and Messrs. Evanoski, Martz and Palkovich will receive special one-time bonuses in December 2014; and

• concurrently with the execution of the merger agreement, WesBanco entered into employment agreements with Ms. Zuschlag, Mr. Evanoski, Mr. Martz and Mr. Palkovich, with such agreements to become effective upon completion of the merger, and a consulting agreement with Mr. Evanoski to commence consulting immediately after the expiration of Mr. Evanoski’s employment agreement.

- 14 -

The WesBanco and ESB boards of directors knew about these additional interests, and considered them, when each board adopted the merger agreement. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Interests of Certain Persons in the Merger” beginning on page [—] for more detailed information about these interests.

when, as and if declared by the WesBanco’s board of directors out of funds legally available for dividends. Historically, WesBanco has paid quarterly cash dividends on its common stock, and its board of directors presently intends to continue to pay regular quarterly cash dividends. WesBanco’s ability to pay dividends to its shareholders in the future will depend on its earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, its ability to service any equity or debt obligations senior to its common stock, including its outstanding trust preferred securities and accompanying junior subordinated debentures, and other factors deemed relevant by its board of directors. In order to pay dividends to shareholders, WesBanco must receive cash dividends from WesBanco Bank. As a result, WesBanco’s ability to pay future dividends will depend upon the earnings of WesBanco Bank, its financial condition and its need for funds. A discussion of the restrictions on WesBanco’s dividend payments is included in WesBanco’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013. See “Where You Can Find More Information About WesBanco and ESB.”

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information is based on the historical financial statements of WesBanco and ESB, and has been prepared to illustrate the financial effect of WesBanco’s merger with ESB. The following unaudited pro forma condensed combined financial information combines the historical consolidated financial position and results of operations of WesBanco and its subsidiaries and of ESB and its subsidiaries, as an acquisition by WesBanco of ESB using the acquisition method of accounting (Accounting Standards Codification (ASC) 805 “Business Combinations”) and giving effect to the related pro forma adjustments described in the accompanying notes. Under the acquisition method of accounting, the assets and liabilities of ESB will be recorded by WesBanco at their respective fair values as of the date the merger is completed. The pro forma financial information should be read in conjunction with WesBanco’s Quarterly Report on Form 10-Q for the period ended September 30, 2014, and Annual Report on Form 10-K for the fiscal year ended December 31, 2013, which are incorporated by reference herein, and ESB’s Quarterly Report on Form 10-Q for the period ended September 30, 2014, and Annual Report on Form 10-K for the fiscal year ended December 31, 2013, which are incorporated by reference herein.

The unaudited pro forma condensed combined financial information set forth below assumes that the merger was consummated on January 1, 2013 for purposes of the unaudited pro forma condensed combined statements of income and September 30, 2014 for purposes of the unaudited pro forma condensed combined balance sheet and gives effect to the merger, for purposes of the unaudited pro forma condensed combined statement of income, as if it had been effective during the entire period presented.

These unaudited pro forma condensed combined financial statements reflect the merger based upon estimated preliminary acquisition accounting adjustments. Actual adjustments will be made as of the effective date of the merger and, therefore, may differ from those reflected in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial statements included herein are presented for informational purposes only and do not necessarily reflect the financial results of the combined company had the companies actually been combined at the beginning of each period presented. This information has been adjusted to give effect to pro forma events that are (i) directly attributable to the acquisition of ESB, (ii) factually supportable, and (iii) expected to have a continuing impact on the combined results. The adjustments included in these unaudited pro forma condensed financial statements are preliminary and may be revised. This information also does not reflect the benefits of the expected cost savings and expense efficiencies, opportunities to earn additional revenue, potential impacts of current market conditions on revenues, or asset dispositions, among other factors, and includes various preliminary estimates and may not necessarily be indicative of the financial position or results of operations that would have occurred if the merger had been consummated on the date or at the beginning of the period indicated or which may be attained in the future. The unaudited pro forma condensed combined financial statements and accompanying notes should be read in conjunction with and are qualified in their entirety by reference to the historical consolidated financial statements and related notes thereto of WesBanco and its subsidiaries and of ESB and its subsidiaries. Such information and notes thereto are incorporated by reference herein.

Notes to the Unaudited Pro Forma Condensed Combined Financial Information

Note A — Basis of Pro Forma Presentation

On October 29, 2014, WesBanco entered into the Agreement and Plan of Merger with ESB. Under the terms of the merger agreement, WesBanco will exchange 0.502 shares of its common stock and $1.76 in cash for each share of ESB common stock. The receipt by ESB shareholders of shares of WesBanco common stock in exchange for their shares of ESB common stock is anticipated to qualify as a tax-free exchange. The transaction, approved by the directors of both companies, currently is valued at $333.3 million. This value is based on WesBanco’s 15 day average closing stock price on October 27, 2014 of $31.66. Considering the range of WesBanco stock prices since the announcement of the merger, the value of the transaction at closing may or may not be materially different from the transaction value included in these pro formas. If the stock price at closing were to increase 10% from the 15 day average closing stock price on October 27, 2014, the resulting deal value would be $362.3 million, with a corresponding $28.5 million increase in goodwill, while a 10% decrease in stock price would result in a $305.4 million deal value and a $28.5 million decrease in goodwill.

The unaudited pro forma condensed combined financial information of WesBanco’s financial condition and results of operations, including per share data, are presented after giving effect to the merger. The pro forma financial information assumes that the merger with ESB was consummated on January 1, 2013 for purposes of the unaudited pro forma condensed combined statements of income and on September 30, 2014 for purposes of the pro forma balance sheet and gives effect to the merger, for purposes of the unaudited pro forma condensed combined statement of income, as if it had been effective during the entire period presented.

The merger will be accounted for using the acquisition method of accounting; accordingly, the difference between the purchase price over the estimated fair value of the assets acquired (including identifiable intangible assets) and liabilities assumed will be recorded as goodwill.

The pro forma financial information includes estimated adjustments to record the assets and liabilities of ESB at their respective fair values and represents management’s estimates based on available information. The pro forma adjustments included herein may be revised as additional information becomes available and as additional analysis is performed. The final allocation of the purchase price will be determined after the merger is completed and after completion of a final analysis to determine the fair values of ESB’s tangible, and identifiable intangible assets and liabilities as of the closing date.

Funding for the merger transaction is included in the pro forma adjustments as follows (in thousands):

Fair value of WesBanco shared to be issued, net of equity issuance costs	$	284,119
Cash consideration for outstanding ESB shares, including all issued stock options		40,203
Pre-existing loan to ESB		9,000
Total purchase price	$	333,322

Note B — Purchase Accounting Adjustments

The pro forma adjustments include the purchase accounting entries to record the merger transaction. The excess of the purchase price over the fair value of the net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments included in the pro forma financial statements are based upon available information, and certain assumptions considered reasonable, and may be revised as additional information becomes available. For purposes of this pro forma analysis, fair value adjustments, other than goodwill, are amortized/accreted on either a straight-line basis or under the sum-of-the-years’ digits method over their estimated average remaining lives. Estimated accretion and amortization on borrowings are based on estimated maturity by type of borrowing. When the actual amortization/accretion is recorded for periods following the merger closing, the effective yield method will be used where appropriate. Tax expense related to the net fair value adjustments is calculated at the statutory 35% tax rate for federal income tax purposes.

- 25 -

Included in the pro forma adjustments are estimated core deposit intangibles of $8.8 million. The core deposit intangibles are separate from goodwill and amortized under the sum-of-the-years’ digits method over an estimated average remaining life of 10 years. When the actual amount of core deposit intangibles is determined as of the date of acquisition, which may be more or less than the estimated amount, the sum-of-the-years’ digits method will be used to record amortization over the intangibles’ actual lives. Estimated goodwill totaling $173.1 million is included in the pro forma adjustments, and is not subject to amortization, but will be tested for impairment at least annually, or when impairment indicators are identified.

The allocation of the purchase price is as follows (in thousands):

The following provides additional details about the methods and assumptions used to determine the pro forma adjustments in the unaudited proforma condensed combined statement of financial position. All adjustments are based on current assumptions and/or valuations, which are subject to change.

(a) Cash and cash equivalents were adjusted by the estimated cash purchase price for the transaction.

(b) Available-for-sale securities were adjusted down to reflect certain credit and liquidity adjustments and to eliminate WesBanco’s pre-existing investment in ESB consisting of 28,881 common shares.

(c) Loans, including loans held for sale, net of the allowance for loan losses and deferred fees and costs were adjusted to reflect credit, liquidity and interest rate estimates resulting in a discount on ESB’s portfolio. Loans were also adjusted to eliminate WesBanco’s pre-existing loan to ESB, included in the purchase price.

- 26 -

(d) Goodwill and other intangible assets were adjusted to remove ESB’s goodwill and core deposit intangible assets and record the estimated goodwill and core deposit intangible asset resulting from the transaction.

(e) Other assets were adjusted to reflect estimated appraisal adjustments, primarily on bank premise and equipment and a real estate joint venture, and to record the estimated deferred tax asset resulting from the transaction.

(f) Deposits were adjusted to reflect current interest rates and spreads resulting in a premium on ESB’s deposits.

(g) Borrowings were adjusted to reflect credit, liquidity and interest rate estimates resulting in a premium on ESB’s borrowings. Additionally other borrowings were adjusted to eliminate ESB’s intercompany borrowing from WesBanco and to eliminate ESB’s ESOP borrowing.

(h) Junior subordinated debt was adjusted down to reflect credit, liquidity and interest rate estimates resulting in a discount on ESB’s trust preferred securities.

(i) Other liabilities were adjusted to include certain pre-acquisition merger-related liabilities and certain contract termination liabilities incurred by ESB.

(j) Equity was adjusted to eliminate ESB’s equity and to reflect the issuance of common shares in the purchase of ESB.

Note C — Projected amortization/accretion of purchase accounting adjustments

The following provides additional details about the methods and assumptions used to determine the pro forma adjustments in the unaudited proforma condensed combined statements of income. All adjustments are based on current assumptions and/or valuations, which are subject to change.

(k) Loan interest income was adjusted to include accretion of the discount on the loan portfolio and to eliminate intercompany interest on WesBanco’s loan to ESB.

(l) Securities interest income was adjusted to include the additional premium amortization on the available-for-sale portfolio resulting from the transaction.

(m) Interest expense on deposits was adjusted to include accretion of the premium on time deposits.

(n) Interest expense on other borrowings was adjusted to reflect amortization of the discount on junior subordinated debt, accretion of the premium on borrowed funds, the elimination of intercompany interest on ESB’s borrowing from WesBanco and to eliminate ESOP borrowing interest.

(o) Other expenses were adjusted to reflect core deposit intangible amortization and adjustments to reduce depreciation expense resulting from an expected write-down of bank premise and equipment.

(p) Income tax expense was adjusted to reflect a statutory tax rate of 35% on the purchase accounting adjustments resulting from the transaction.

- 27 -

(1) Estimated accretion and amortization of fair value adjustments are accreted or amortized on either a straight-line basis or under the sum-of-the-years’ digits method over the estimated average or actual remaining life: 5 years for securities, 16 years for loans ($4.1M of gross mark assumed to be non-accretable), 10 years for core deposit intangibles, 22.5 years for bank premises and equipment, 1.5 years for certificate of deposits, 4 years for other borrowings and 20 years for junior subordinated debt. (Note: When the actual amortization is recorded for periods following closing of the transaction, the interest method may also be used.) The restructuring of borrowings, loans, securities and/or junior subordinated debt may alter the accretion and amortization amounts included in this pro forma analysis.

(2) Accretion and amortization estimates for 2015 assumes the acquisition closes on January 1, 2015.

(3) The estimated unamortized premium on the ESB available-for-sale securities portfolio at closing is estimated to be $9 million and the unrealized gain $25 million. Upon acquisition the unrealized gain is effectively capitalized and recognized as additional premium which must be amortized over the remaining life of the portfolio. The resulting increase in premium amortization is reflected in this pro forma.

The actual effect of purchase accounting adjustments on the future pre-tax income of WesBanco will differ from these estimates based on the closing date estimates of fair values and the use of different amortization methods than assumed above.

Note D — Cost Savings and Merger-Related Costs

Estimated cost savings, expected to approximate 50% of ESB’s annualized pre-tax operating expenses, are excluded from this pro forma analysis. Cost savings are estimated to be realized at 75% in the first full year after the acquisition with the remainder expected to be recognized in subsequent years. In addition, estimated merger-related costs are not included in the pro forma combined statements of income since they will be recorded in the combined results of income as they are incurred prior to or after completion of the merger and are not indicative of what the historical results of the combined company would have been had the companies been actually combined during the periods presented. Pre-tax merger-related expenses are estimated to be $25.7 million, of which $11.5 million is related to ESB pre-acquisition expenses and reflected in the proforma financial statements as an acquired liability. See Note B, Purchase Accounting Adjustments, for additional information.

Note E — Non-GAAP Financial Measures

The following non-GAAP financial measures used by WesBanco and ESB provide information useful to investors in understanding operating performance and trends, and facilitate comparisons with the performance of peers.

COMPARATIVE PER SHARE DATA

(Unaudited)

The following tables set forth the basic earnings, diluted earnings, cash dividends and book value per common share data for WesBanco and ESB on a historical basis, on a pro forma combined basis, and on a per equivalent ESB share basis, as of or for the nine month period ending September 30, 2014, and as of or for the fiscal year ended December 31, 2013.

The pro forma data was derived by combining the historical consolidated financial information of WesBanco and ESB using the acquisition method of accounting for business combinations and assumes the transaction is completed as contemplated. The pro forma and pro forma-equivalent per share information gives effect to the merger as if the transactions had been effective on the dates presented, in the case of the book value data, and as if the transactions had become effective on January 1, 2013, in the case of the earnings per share and dividends declared data. The unaudited pro forma data in the tables assume that the merger is accounted for using the acquisition method of accounting and represent a current estimate based on available information of the combined company’s results of operations. The pro forma financial adjustments record the assets and liabilities of ESB at their estimated fair values and are subject to adjustment as additional information becomes available and as additional analyses are performed. See “Unaudited Pro Forma Condensed Combined Financial Information” on page [—]. The information in the following table is based on, and should be read together with, the financial information and financial statements of WesBanco and ESB incorporated by reference in this joint proxy statement/prospectus. See “Where You Can Find More Information About WesBanco and ESB” on page [—].

This information is presented for illustrative purposes only. You should not rely on the pro forma combined or pro forma equivalent amounts as they are not necessarily indicative of the operating results or financial position that would have occurred if the merger had been completed as of the dates indicated, nor are they necessarily indicative of the future operating results or financial position of the combined company. The pro forma information, although helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect the benefits of expected cost savings, opportunities to earn additional revenue, the impact of restructuring and merger-related costs, or other factors that may result as a consequence of the merger and, accordingly, does not attempt to predict or suggest future results.

RISK FACTORS

In addition to the other information included in and incorporated by reference into this joint proxy statement/prospectus, including the matters addressed in “Cautionary Statement Regarding Forward-Looking Statements,” and the risk factors included in WesBanco’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013, and ESB’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013, you should carefully consider the following risk factors before deciding whether to vote to approve the issuance of shares of WesBanco common stock in connection with the merger, in the case of WesBanco shareholders, or to vote to adopt the merger agreement, in the case of ESB shareholders. For further discussion of these and other risk factors, please see WesBanco’s and ESB’s periodic reports and other documents incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information About WesBanco and ESB” beginning on page [—].

Because the market price of WesBanco common stock may fluctuate, ESB shareholders cannot be certain of the market value of the WesBanco common stock that they will receive in the merger.

Upon completion of the merger, each share of ESB common stock will become the right to receive (i) 0.502 of a share of WesBanco common stock and (ii) $1.76 in cash, without interest. Accordingly, upon completion of the merger, ESB shareholders will have the right to receive WesBanco common stock at an exchange ratio of 0.502 of a share of WesBanco common stock for each share of ESB common stock owned. Any change in the price of WesBanco common stock prior to completion of the merger will affect the market value of the stock that ESB shareholders will receive on the date of the merger. Stock price changes may result from a variety of factors, including general market and economic conditions, changes in WesBanco’s businesses, operations and prospects, and regulatory considerations. WesBanco and ESB shareholders are urged to obtain current market quotations for WesBanco and ESB common stock when deciding how to vote.

If the price of WesBanco common stock declines, ESB shareholders may receive less value for their shares upon completion of the merger than the value calculated pursuant to the exchange ratio on the date the merger agreement was executed, on the date of this joint proxy statement/prospectus or on the date of the ESB shareholder meeting. For example, based on the range of closing prices of WesBanco common stock during the period from October 29, 2014, the last full trading day before public announcement of the merger, through [—], 2014, the last practicable full trading day prior to the date of this joint proxy statement/prospectus, the exchange ratio represented a value ranging from a high of $[—] on [—], 2014 to a low of $[—] on [—], 2014 for each share of ESB common stock. Because the date the merger is completed will be later than the date of the WesBanco and ESB special meeting, WesBanco and ESB shareholders will not know what the market value of WesBanco common stock will be upon completion of the merger when voting at the WesBanco or ESB special meeting, as applicable.

The combined company will incur significant transaction and merger-related costs in connection with the merger.

WesBanco and ESB expect to incur costs associated with combining the operations of the two companies. WesBanco and ESB have just recently begun collecting information in order to formulate detailed integration plans to deliver planned synergies. Additional unanticipated costs may be incurred in the integration of the businesses of WesBanco and ESB. Whether or not the merger is consummated, WesBanco and ESB will incur substantial expenses, such as legal, accounting, printing and financial advisory fees, in pursuing the merger. Although WesBanco and ESB expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses may offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

- 32 -

If the merger is not completed, WesBanco and ESB will have incurred substantial expenses without its shareholders realizing the expected benefits of the merger.

WesBanco and ESB have each incurred substantial expenses in connection with the transactions described in this joint proxy statement/prospectus, which are charged to earnings as incurred. If the merger is not completed, these expenses will still be charged to earnings even though WesBanco and ESB would not have realized the expected benefits of the merger. There can be no assurance that the merger will be completed.

WesBanco may not be able to successfully integrate ESB or to realize the anticipated benefits of the merger.

The merger involves the combination of two companies that previously have operated independently. A successful combination of the operations of the two entities will depend substantially on WesBanco’s ability to consolidate operations, systems and procedures and to eliminate redundancies and reduce costs of the combined operations. WesBanco may not be able to combine the operations of ESB and WesBanco without encountering difficulties, such as:

• the loss of key employees and customers;

• the disruption of operations and business;

• the inability to maintain and increase competitive presence;

• deposit attrition, customer loss and revenue loss;

• possible inconsistencies in standards, control procedures and policies;

• unexpected problems with costs, operations, personnel, technology and credit; and/or

• problems with the assimilation of new operations, sites or personnel, which could divert resources from regular banking operations.

Additionally, general market and economic conditions or governmental actions affecting the financial industry generally may inhibit the successful integration of ESB and WesBanco.

Further, WesBanco and ESB entered into the merger agreement with the expectation that the merger will result in various benefits including, among other things, benefits relating to enhanced revenues, a strengthened market position for the combined company, cross selling opportunities, technology, cost savings and operating efficiencies. Achieving the anticipated benefits of the merger is subject to a number of uncertainties, including whether WesBanco integrates ESB in an efficient and effective manner, and general competitive factors in the marketplace. Failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy and could materially impact WesBanco’s business, financial condition and operating results. Finally, any cost savings that are realized may be offset by losses in revenues or other charges to earnings.

The merger agreement may be terminated in accordance with its terms and the merger may not be completed.

The merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger. Those conditions include, among others: adoption of the merger agreement by ESB shareholders, approval of the issuance of shares of WesBanco common stock in connection with the merger by WesBanco shareholders; regulatory approvals, absence of orders prohibiting the completion of the merger, effectiveness of the registration statement of which this joint proxy statement/prospectus is a part, approval of the shares of WesBanco common stock to be issued to ESB shareholders for listing on the Nasdaq Global Select Market, the continued accuracy of the representations and warranties by both parties and the performance by both parties of their covenants and agreements, and the receipt by both parties of legal opinions from their respective tax counsels. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of

- 33 -

the Merger Agreement) — Termination of the Merger Agreement” beginning on page [—] for a more complete discussion of the circumstances under which the merger agreement could be terminated. Therefore, the conditions to closing of the merger may not be fulfilled and the merger may not be completed.

Termination of the merger agreement could negatively affect ESB.

If the merger agreement is terminated, there may be various consequences, including:

• ESB’s businesses may have been adversely impacted by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger; and

• the market price of ESB common stock might decline to the extent that the current market price reflects a market assumption that the merger will be completed.

If the merger agreement is terminated and ESB’s board of directors seeks another merger or business combination, ESB shareholders cannot be certain that ESB will be able to find a party willing to offer equivalent or more attractive consideration than the consideration WesBanco has agreed to provide in the merger.

If the merger agreement is terminated, ESB may be required to pay a break-up fee of $11,354,000 to WesBanco under certain circumstances. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Termination Fee” beginning on page [—].

The merger agreement limits ESB’s ability to pursue alternatives to the merger.

The merger agreement contains provisions that, subject to very narrow exceptions, limit ESB’s ability to discuss, facilitate or enter into agreements with third parties to acquire it. If ESB avails itself of those limited exceptions, it could be obligated to pay WesBanco a break-up fee of $11,354,000 under certain specified circumstances. These provisions could discourage a potential competing acquiror that might have an interest in acquiring ESB from proposing or considering an acquisition of it even if that potential acquiror were prepared to pay a higher price to shareholders than the merger consideration.

ESB will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainties about the effect of the merger on employees and customers may have an adverse effect on ESB and consequently on WesBanco. These uncertainties may impair ESB’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with ESB to seek to change existing business relationships with ESB. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the business, ESB’s business prior to the merger and the combined company’s business following the merger could be negatively impacted. In addition, the merger agreement restricts ESB from making certain acquisitions and taking other specified actions until the merger occurs without the consent of WesBanco. These restrictions may prevent ESB from pursuing business opportunities that may arise prior to the completion of the merger. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Conduct of Business Prior to the Merger” beginning on page [—] for a description of certain of the restrictive covenants applicable to ESB.

The need for regulatory approvals may delay the date of completion of the merger or may diminish the benefits of the merger.

WesBanco is required to obtain the approvals of certain bank regulatory agencies prior to completing the merger. Satisfying any requirements of these regulatory agencies may delay the date of completion of the merger. The requisite regulatory approvals may not be received at all (in which case the merger could not be completed),

- 34 -

may not be received in a timely fashion, or may contain conditions or restrictions on completion of the merger that cannot be satisfied. In addition, you should be aware that, as in any transaction, it is possible that, among other things, restrictions on the combined operations of the two companies, including divestitures, may be sought by governmental agencies as a condition to obtaining the required regulatory approvals. This may diminish the benefits of the merger to the combined company or have an adverse effect on the combined company following the merger. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Regulatory Approvals” on page [—].

Future results of the combined companies may materially differ from the pro forma financial information presented in this joint proxy statement/prospectus.

WesBanco and ESB may not be able to integrate their operations without encountering difficulties including, without limitation, the loss of key employees and customers, the disruption of their respective ongoing businesses or possible inconsistencies in standards, controls, procedures and policies. Future results of the combined company may be materially different from those shown in the pro forma financial statements that only show a combination of the historical results of WesBanco and ESB. We have estimated that the combined company will record approximately $26 million of pre-tax merger-related costs. The costs may be higher or lower than we have estimated, depending upon how costly or difficult it is to integrate the two companies. Furthermore, these costs may decrease the capital of the combined company that could be used for profitable, income-earning investments in the future.

Additionally, in determining that the merger is in the best interests of WesBanco and ESB and its shareholders, the respective boards of directors of WesBanco and ESB considered that enhanced earnings may result from the consummation of the merger, including from reduction of duplicate costs, improved efficiency and cross-marketing opportunities. However, there can be no assurance that any enhanced earnings will result from the merger.

ESB shareholders will have less influence as a shareholder of WesBanco than as a shareholder of ESB.

ESB shareholders currently have the right to vote in the election of the board of directors of ESB and on other matters affecting ESB. Based upon the number of shares of ESB common stock outstanding as of the ESB record date, the current shareholders of ESB as a group will own approximately [—]% of the voting power of the combined organization immediately after the merger. When the merger occurs, each ESB shareholder will become a shareholder of WesBanco with a percentage ownership of the combined organization much smaller than such shareholder’s percentage ownership of ESB. Because of this, ESB shareholders will have less influence on the management and policies of WesBanco than they now have on the management and policies of ESB.

Directors and officers of ESB have interests in the merger that differ from the interests of non-management ESB shareholders.

The executive officers of ESB and WesBanco, with the assistance of their respective legal counsel and financial advisors, negotiated the terms of the merger agreement, the ESB and WesBanco boards of directors approved the merger agreement and the WesBanco board of directors recommends that WesBanco shareholders vote to approve the issuance of WesBanco common stock in connection with the merger while the ESB board of directors recommends that ESB shareholders vote to adopt the merger agreement. In considering these facts and the other information included in this joint proxy statement/prospectus or incorporated by reference in this joint proxy statement/prospectus, shareholders should be aware that ESB’s directors and executive officers have economic interests in the merger other than their interests as shareholders. For example, ESB is party to employment agreements or change in control agreements with its executive officers (one of whom, Charlotte A. Zuschlag, is also a director), which provide for, among other things, cash payments following a change of control that is coupled with a termination of employment without cause. In addition, upon completion of the merger, Charlotte A. Zuschlag, ESB’s President and Chief Executive Officer, and Ronald W. Owen, a director of ESB

- 35 -

Bank will be appointed to the board of directors of WesBanco. Also, WesBanco and ESB have entered into a separation agreement and a non-competition agreement with each of Charlotte A. Zuschlag, Charles P. Evanoski, Frank D. Martz and Todd F. Palkovich, and WesBanco has entered into employment agreements with Ms. Zuschlag, Mr. Evanoski, Mr. Martz and Mr. Palkovich and a consulting agreement with Mr. Evanoski to commence consulting immediately after the expiration of Mr. Evanoski’s employment agreement. The merger agreement also provides for the accelerated vesting upon completion of the merger of all outstanding stock options and restricted stock awards which remain unvested immediately prior to completion of the merger. WesBanco has also created a retention bonus pool for key employees to ensure continuity through the conversion of the data processing system of ESB. The merger agreement also provides that WesBanco will continue indemnification of ESB’s current and former directors and executive officers and, for six years after completion of the merger, provide certain directors’ and officers’ insurance for these individuals. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Interests of Certain Persons in the Merger” beginning on page [—].

WesBanco and ESB shareholders do not have dissenters’ or appraisal rights in the merger.

Dissenters’ or appraisal rights are statutory rights that, if applicable under law, enable shareholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the merger consideration offered to shareholders in connection with the extraordinary transaction. Under Pennsylvania law, shareholders do not have dissenters’ or appraisal rights with respect to shares of any class of stock which, at the record date fixed to determine shareholders entitled to receive notice of and to vote at the meeting of shareholders at which a merger or consolidation was acted on, were listed on a national securities exchange. Because ESB’s common stock is listed on the Nasdaq Global Select Market, a national securities exchange, holders of ESB common stock will not be entitled to dissenters’ or appraisal rights in the merger with respect to their shares of ESB common stock. Similarly, under West Virginia law, WesBanco shareholders do not have dissenters’ or appraisal rights in connection with the proposal to approve the issuance of shares of Wesbanco common stock in the merger.

Following the merger, a high percentage of the combined company’s loan portfolio will remain in West Virginia, Ohio, and Pennsylvania and in commercial and residential real estate. Deteriorations in economic conditions in this area or in the real estate market generally could be more harmful to the combined company compared to more diversified institutions.

As of September 30, 2014, approximately 30%, of WesBanco’s loan portfolio was comprised of residential real estate loans, and 49% was comprised of commercial real estate loans. As a result of the merger, the combined company’s loan portfolio, as of September 30, 2014, would have been 37% residential real estate loans and 43% commercial real estate loans.

Inherent risks of commercial real estate (“CRE”) lending include the cyclical nature of the real estate market, construction risk and interest rate risk. The cyclical nature of real estate markets can cause CRE loans to suffer considerable distress. During these times of distress, a property’s performance can be negatively affected by tenants’ deteriorating credit strength and lease expirations in times of softening demand caused by economic deterioration or over-supply conditions. Even if borrowers are able to meet their payment obligations, they may find it difficult to refinance their full loan amounts at maturity due to declines in property value. Other risks associated with CRE lending include regulatory changes and environmental liability. Regulatory changes in tax legislation, zoning or similar external conditions including environmental liability may affect property values and the economic feasibility of existing and proposed real estate projects.

The combined company’s CRE loan portfolio will be concentrated in West Virginia, Ohio and Pennsylvania. There are a wide variety of economic conditions within the local markets of the three states in which most of the combined company’s CRE loan portfolio will be situated. Rates of employment, consumer loan demand, household formation, and the level of economic activity can vary widely from state to state and

- 36 -

among metropolitan areas, cities and towns. Metropolitan markets comprise various submarkets where property values and demand can be affected by many factors, such as demographic makeup, geographic features, transportation, recreation, local government, school systems, utility infrastructure, tax burden, building-stock age, zoning and building codes, and available land for development. Despite the merger, as a result of the continued high concentration of the combined company’s loan portfolio, the combined company may be more sensitive, compared to more diversified institutions, to future disruptions in, and deterioration of, this market, which could lead to losses which could have a material adverse effect on the business, financial condition and results of operations of the combined company.

THE SPECIAL MEETING OF WESBANCO SHAREHOLDERS

General

This section contains information about the special shareholder meeting WesBanco has called to consider and vote on the (i) approval of the issuance of shares of WesBanco common stock in connection with the merger and (ii) approval of the adjournment of the WesBanco special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the issuance of shares of WesBanco common stock in connection with the merger, at the time of the WesBanco special meeting. WesBanco is mailing this joint proxy statement/prospectus to you on or about [—], 2014. Together with this joint proxy statement/prospectus, WesBanco is also sending to its shareholders a notice of the WesBanco special meeting and a form of proxy that WesBanco’s board of directors is soliciting for use at the WesBanco special meeting and at any adjournments of the meeting.

A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A and is incorporated by reference into this document in its entirety. You should read the entire merger agreement carefully.

Date, Time and Place of the Special Meeting

The WesBanco special meeting will be held at [—], on [—] 2015, at [—] Eastern Time

Record Date; Stock Entitled to Vote; Quorum

Only holders of record of WesBanco common stock on [—], 201[—], which we refer to as the WesBanco record date, will be entitled to notice of and to vote at the WesBanco special meeting and any adjournments of the WesBanco special meeting. On the WesBanco record date, there were [—] shares of WesBanco common stock outstanding and entitled to vote at the WesBanco special meeting. Owners of record of WesBanco common stock on the WesBanco record date are entitled to one vote per share at the WesBanco special meeting.

A quorum of WesBanco shareholders is necessary to have a valid meeting of shareholders. The presence, in person or by proxy, of the holders of at least a majority of the shares of WesBanco common stock outstanding as of the WesBanco record date and entitled to vote is necessary to constitute a quorum at the WesBanco special meeting. Both abstentions and broker non-votes count as present for establishing a quorum. An abstention occurs when a shareholder attends a meeting, either in person or by proxy, but abstains from voting. A broker non-vote occurs on an item when a broker is not permitted to vote on that item without instructions from the beneficial owner of the shares and no instructions are given.

Beneficial Ownership of WesBanco Officers, Directors and Affiliates

On the WesBanco record date, the directors, executive officers and affiliates of WesBanco owned or controlled the vote of [—] shares of WesBanco common stock, constituting approximately [—]% of the outstanding shares of WesBanco common stock.

Voting of Proxies

WesBanco shareholders may submit the accompanying proxy by telephone, the Internet or by returning the proxy by mail if you are unable to attend the WesBanco special meeting in person or wish to have your WesBanco shares voted by proxy even if you attend the WesBanco meeting. All shares of WesBanco common stock represented at the WesBanco special meeting by properly executed proxies received prior to or at the WesBanco special meeting, and not revoked, will be voted at the WesBanco special meeting in accordance with the instructions on the proxies. If you properly execute a proxy but include no voting instructions, your WesBanco shares will be voted “FOR” (i) the approval of the issuance of shares of WesBanco common stock in connection with the merger; and (ii) approval of the adjournment of the WesBanco special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the issuance of shares of WesBanco common stock in connection with the merger at the time of the WesBanco special meeting.

If your shares are held in “street name” (i.e., in the name of a broker, bank or other record holder), you must direct the record holder how to vote your WesBanco shares in connection with the merger. Your broker will send you directions explaining how you can direct your broker to vote.

The WesBanco board of directors does not know of any matters, other than as described in the notice of the WesBanco special meeting, which are to come before the WesBanco special meeting. If any other matters are properly presented at the WesBanco special meeting for action, the persons named in the enclosed form of proxy will have the authority to vote on those matters in their discretion.

Revocation of Proxies

If you give a proxy, you have the right to revoke it at any time before it is voted. You may revoke your proxy by (i) filing with the Secretary of WesBanco a written notice of revocation that is received prior to the vote at the WesBanco special meeting and that bears a later date than the proxy, (ii) duly executing a later dated proxy relating to the same WesBanco shares and delivering it to the Secretary of WesBanco before the vote at the WesBanco special meeting, (iii) submitting a later dated proxy by telephone or the Internet, before the vote at the WesBanco special meeting, or (iv) attending the WesBanco special meeting and voting in person. Your attendance at the WesBanco special meeting will not, in and of itself, revoke your proxy. Any written notice of revocation or subsequent dated proxy should be sent so as to be delivered to Wesbanco, Inc., 1 Bank Plaza, Wheeling, West Virginia 26003, Attention: Corporate Secretary, or hand delivered to the foregoing representative of WesBanco. For a notice of revocation or later proxy to be valid, it must actually be received by WesBanco prior to the vote of the WesBanco shareholders.

If your shares are held by a broker in street name and you wish to change the instructions you have given your broker about how to vote your WesBanco shares, or you wish to attend the special meeting and vote in person, you must follow the instructions provided by your broker.

Expenses of Solicitation of Proxies

WesBanco will bear the entire cost of soliciting proxies from WesBanco shareholders. WesBanco has engaged a professional proxy solicitation firm, Georgeson Inc. (“Georgeson”), to assist in soliciting proxies for use at the WesBanco special meeting. WesBanco will pay Georgeson a fee of $9,000 and will reimburse Georgeson for its out-of-pocket expenses. In addition to solicitation by Georgeson and use of the mail, proxies

- 39 -

may be solicited by directors, officers and employees of WesBanco in person or by telephone, telegram or other means of communication. These directors, officers and employees will not be additionally compensated but may be reimbursed for out-of-pocket expenses they incur in connection with the solicitation. Arrangements will also be made with brokerage houses, custodians, nominees and fiduciaries for the forwarding of solicitation materials to the beneficial owners of WesBanco common stock held of record by such persons. WesBanco may reimburse these custodians, nominees and fiduciaries for reasonable out-of-pocket expenses they incur.

Recommendation of WesBanco Board of Directors

The WesBanco board of directors believes that the merger is in the best interests of WesBanco and its shareholders, and unanimously recommends that the shareholders of WesBanco vote “FOR” the approval of the issuance of shares of WesBanco common stock in connection with the merger; and “FOR” the adjournment of the WesBanco special meeting, if necessary, to solicit additional proxies in favor of the approval of the issuance of shares of WesBanco common stock in connection with the merger.

In determining whether to approve the merger agreement and recommend approval of the issuance of shares of WesBanco common stock in connection with the merger to the WesBanco shareholders, WesBanco’s board considered the factors described under “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — WesBanco’s Reasons for the Merger.”

ESB is mailing this joint proxy statement/prospectus to you on or about [—], 2014. Together with this joint proxy statement/prospectus, ESB is also sending to its shareholders a notice of the ESB special meeting and a form of proxy that ESB’s board of directors is soliciting for use at the ESB special meeting and at any adjournments of the meeting.

A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A and is incorporated by reference into this document in its entirety. You should read the entire merger agreement carefully.

Both abstentions and broker non-votes count as present for establishing a quorum. An abstention occurs when a shareholder attends a meeting, either in person or by proxy, but abstains from voting. A broker non-vote occurs on an item when a broker is not permitted to vote on that item without instructions from the beneficial owner of the shares and no instructions are given.

Required Vote

Adopt the Merger Agreement. Adoption of the merger agreement requires the affirmative vote of a majority of the votes cast by the holders of ESB common stock entitled to vote thereon at the ESB special meeting at which a quorum is present. Accordingly, we urge you to complete, date and sign the accompanying proxy card and return it promptly in the enclosed postage-paid envelope.

When considering the recommendation of the ESB board of directors that ESB shareholders vote in favor of adoption of the merger agreement, you should be aware that certain of ESB’s executive officers and directors have interests in the merger that may be different from, or in addition to, their interests as shareholders and the interests of ESB shareholders generally.

Expenses of Solicitation of Proxies

ESB has engaged a professional proxy solicitation firm, Morrow & Co., LLC (“Morrow”), to assist in soliciting proxies for use at the ESB special meeting. Under the terms of the merger agreement, WesBanco has agreed to pay the fees and expenses of Morrow. Morrow will be paid a fee of $6,000 plus reimbursement for out-of-pocket expenses. Other than with respect to Morrow, ESB will bear the entire cost of soliciting proxies from ESB shareholders. In addition to solicitation by Morrow and by use of the mail, proxies may be solicited by directors, officers and employees of ESB in person or by telephone, telegram or other means of communication. These directors, officers and employees will not be additionally compensated but may be reimbursed for out-of-pocket expenses they incur in connection with the solicitation. Arrangements will also be made with brokerage houses, custodians, nominees and fiduciaries for the forwarding of solicitation materials to the beneficial owners of ESB common stock held of record by such persons. ESB may reimburse these custodians, nominees and fiduciaries for reasonable out-of-pocket expenses they incur.

DO NOT SEND YOUR STOCK CERTIFICATES WITH YOUR PROXY CARD.

Recommendation of ESB Board of Directors

The ESB board of directors believes that the merger is in the best interests of ESB and its shareholders, and unanimously recommends that the shareholders of ESB vote “FOR” adoption of the merger agreement; “FOR” approval, in a non-binding, advisory vote, of the compensation payable to the named executive officers of ESB in connection with the merger; and “FOR” the adjournment of the ESB special meeting, if necessary, to solicit additional proxies in favor of the adoption of the merger agreement.

In the course of reaching its decision to adopt the merger agreement and the transactions contemplated thereby, the ESB board of directors, among other things, consulted with its legal advisors regarding the legal terms of the merger agreement and with its financial advisor as to the fairness, from a financial point of view, of the consideration to be paid to ESB shareholders. For a discussion of the factors considered by the ESB board of directors in reaching its conclusion, see “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — ESB’s Reasons for the Merger.”

WESBANCO PROPOSAL NO. 1 (APPROVAL OF THE SHARE ISSUANCE) AND ESB PROPOSAL NO. 1 (ADOPTION OF THE MERGER AGREEMENT)

The following summarizes material provisions of the merger agreement, a copy of which is attached to this joint proxy statement/prospectus as Annex A and which we incorporate by reference into this document. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. We encourage you to read carefully the merger agreement in its entirety, as the rights and obligations of the parties are governed by the express terms of the merger agreement and not by this summary or any other information contained in this proxy statement. Factual disclosures about WesBanco and ESB contained in this joint proxy statement/prospectus or in the companies’ public reports filed with the SEC may supplement, update or modify the factual disclosures about the companies contained in the merger agreement.

The description of the merger agreement in this joint proxy statement/prospectus has been included to provide you with information regarding its terms. The merger agreement contains representations, warranties, covenants and agreements made by WesBanco and ESB as of specific dates that were made for purposes of that contract between the parties and are subject to qualifications and limitations, including by information in disclosure schedules that the parties exchanged in connection with the execution of the merger agreement. In addition, certain representations and warranties may be subject to contractual standards of materiality different from those generally applicable to shareholders, or may have been used for the purpose of allocating risk between the parties rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this joint proxy statement/prospectus, may have changed since the date of the merger agreement. Shareholders are not third-party beneficiaries under the merger agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of WesBanco or ESB.

General

WesBanco’s and ESB’s boards of directors have approved the merger agreement. The merger agreement provides that ESB will merge with and into WesBanco, with WesBanco being the surviving corporation. Following the merger, ESB Bank, a Pennsylvania state-chartered savings bank which is ESB’s main operating subsidiary, will merge with and into WesBanco Bank, a West Virginia banking corporation which is WesBanco’s main operating subsidiary (the “bank merger”). The Articles of Incorporation and Bylaws of WesBanco and WesBanco Bank immediately prior to the merger will constitute the Articles of Incorporation and Bylaws of WesBanco and WesBanco Bank following the merger.

What ESB Shareholders Will Receive in the Merger

If the merger is completed, for each share of ESB common stock that an ESB shareholder owns that shareholder will receive (i) 0.502 of a share of WesBanco common stock and (ii) $1.76 in cash, without interest, subject to possible adjustment in accordance with the terms of the merger agreement as discussed below.

Possible Exchange Ratio Adjustments. The 0.502 exchange ratio is subject to adjustment in the event that certain termination provisions, based on the market price of WesBanco’s common stock and the value of the Nasdaq Bank Index, are triggered and the ESB board of directors elects to terminate the merger agreement. ESB’s right to terminate the merger agreement would arise if the average closing price of WesBanco common stock during the ten (10) consecutive trading days ending on the Determination Date (as defined below on page [—]) is less than $27.98 per share and WesBanco common stock underperforms an index of financial institution stocks, the Nasdaq Bank Index, by more than 15%. However, ESB would not have the right to terminate the merger agreement if WesBanco elects to make a compensating adjustment in the exchange ratio. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Termination of the Merger Agreement” beginning on page [—] for a description of the possible

- 44 -

exchange ratio adjustments that may result from this termination provision. In addition, the merger agreement provides that the exchange ratio will be adjusted in the event WesBanco changes the number of shares of WesBanco common stock issued and outstanding prior to the effective time of the merger as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other like changes in WesBanco’s capitalization.

Effects of the Merger

The merger shall become effective as set forth in the articles of merger that shall be filed with the West Virginia Secretary of State and Department of State of the Commonwealth of Pennsylvania. At that time, the separate existence of ESB will cease and WesBanco will be the surviving corporation. The assets, liabilities and capital of ESB will be merged with those of WesBanco and those assets, liabilities and capital will then constitute part of the assets, liabilities and capital of WesBanco. WesBanco will continue to operate under its articles of incorporation and bylaws effective as of immediately prior to the merger, and the officers and directors of WesBanco will continue as the officers and directors of the surviving corporation, except that Charlotte A. Zuschlag, ESB’s President and Chief Executive Officer, and Ronald W. Owen, a current director of ESB Bank, will be appointed to the board of directors of WesBanco effective as of the effective time of the merger. See “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Interests of Certain Persons in the Merger” beginning on page [—]. The Articles of Incorporation and Bylaws of WesBanco will be unaffected by the merger. The tenure of the directors and officers of WesBanco immediately prior to the merger will be unaffected by the merger.

At the effective time of the merger, each share of ESB common stock issued and outstanding immediately prior to the time the merger becomes effective will be converted automatically into the right to receive the merger consideration. Shares of ESB common stock held by ESB in its treasury or beneficially owned by WesBanco (other than in a fiduciary capacity by them for others) will not be exchanged for the merger consideration in the merger. Instead, these shares will be canceled and retired. In addition, at or prior to the effective time of the merger, all restricted shares of ESB common stock will be vested and no longer subject to restrictions and will be converted into the right to receive the merger consideration at the effective time of the merger.

After the merger becomes effective, each certificate evidencing shares of ESB common stock will be deemed to evidence only the right to receive the merger consideration and, under certain circumstances, dividends on shares of ESB common stock with a record date prior to the completion of the merger and dividends on shares of WesBanco common stock with a record date after the completion of the merger. The holder of an unexchanged certificate will not receive any dividend or other distribution payable by WesBanco until the certificate has been exchanged.

Exchange and Payment Procedures

At least one business day prior to the effective time of the merger, WesBanco will deposit with Computershare Investor Services, LLC, the Exchange Agent, (i) book entry shares representing the aggregate number of shares of WesBanco common stock issuable pursuant to the merger agreement in exchange for all of the shares of ESB common stock outstanding immediately prior to the effective time of the merger, (ii) immediately available funds equal to the aggregate amount of cash, without interest, payable by WesBanco pursuant to the merger agreement in exchange for all of the shares of ESB common stock outstanding immediately prior to the effective time of the merger and (iii) cash to be paid to ESB shareholders in lieu of fractional shares of WesBanco common stock.

As soon as practicable after the effective time of the merger and in no event more than five business days thereafter, the Exchange Agent will mail each holder of record of ESB common stock a letter of transmittal containing instructions for use in effecting the surrender of certificates representing shares of ESB common stock

- 45 -

in exchange for the merger consideration or cash in lieu of fractional shares. After the effective time of the merger, each holder of an ESB stock certificate, other than certificates representing treasury shares (as defined in the merger agreement), who has surrendered such certificate or who has provided customary affidavits and indemnification regarding the loss or destruction of such certificate, together with duly executed transmittal materials, to the Exchange Agent, will be entitled to receive, for each share of ESB common stock, (i) 0.502 of a share of WesBanco common stock, (ii) $1.76 in cash, without interest, and (iii) cash in lieu of any fractional shares of WesBanco common stock to which such holder is otherwise entitled. WesBanco will have no obligation to deliver the merger consideration or cash in lieu of fractional shares to any ESB shareholder until the ESB shareholder surrenders his certificates representing his shares of ESB common stock.

If an ESB stock certificate has been lost, stolen or destroyed, the Exchange Agent will issue the consideration properly payable under the merger agreement upon receipt of an affidavit of that fact by the claimant. WesBanco may require the claimant to post a bond in a reasonable amount as an indemnity against any claim that may be made against WesBanco with respect to the claimant’s lost, stolen or destroyed ESB stock certificate.

ESB common stock certificates may be exchanged for merger consideration and cash in lieu of fractional shares of WesBanco common stock through the Exchange Agent for up to 12 months after the completion of the merger. At the end of that period, the Exchange Agent will return any WesBanco shares and cash to WesBanco. Any holders of ESB common stock certificates who have not exchanged their certificates for the merger consideration before that date will then be entitled to look only to WesBanco to seek payment of the merger consideration, any cash in lieu of fractional shares of WesBanco common stock and any unpaid dividends or distributions payable to such holder pursuant to the merger agreement. Neither ESB nor WesBanco will be liable to any former holder of ESB common stock for any merger consideration that is paid to a public official pursuant to any applicable abandoned property, escheat or similar laws.

Following the effective time of the merger, there shall be no transfers on the stock transfer books of ESB other than to settle transfers of ESB common stock that occurred prior to the effective time of the merger.

Benefit Agreements

Employee Stock Ownership Plan. The ESB Employee Stock Ownership Plan (the “ESOP”) will be terminated as of the effective time of the merger by ESB in accordance with its terms. Until the ESOP is terminated, ESB will continue to make contributions to the ESOP in accordance with applicable accruals and in the ordinary course of business. The accounts of all participants and beneficiaries in the ESOP will become fully vested as of the effective time of the merger. Any shares of ESB common stock held in the ESOP shall be converted into the right to receive 0.502 of a share of WesBanco common stock plus $1.76 in cash, without interest, for each share of ESB common stock, which amounts with respect to unallocated shares of ESB common stock shall first be used to repay the then outstanding balance of the ESOP loan in its entirety, with the excess amount of the merger consideration received with respect to the unallocated shares of ESB common stock to be allocated proportionately to all holders of ESOP accounts based on their account balances as of the beginning of the plan year in which the ESOP is terminated. The merger agreement also requires ESB to file all necessary documents with the IRS for a determination letter for termination of the ESOP as soon as practicable. As soon as practicable following the effective time or the receipt of a favorable determination letter from the IRS regarding the qualified status of the ESOP upon its termination, the account balances in the ESOP shall be either distributed to participants and beneficiaries or transferred to an eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct. WesBanco has agreed to permit ESB employees who become WesBanco employees following completion of the merger to roll over their account balances in the ESOP to the WesBanco Employee Stock Ownership and 401(k) Plan (the “KSOP”).

401(k) Plan. Pursuant to the terms of the merger agreement, ESB is required to terminate its 401(k) Plan, immediately prior to the effective time of the merger. Until the 401(k) Plan is terminated, ESB will continue to

- 46 -

make contributions to the 401(k) Plan in accordance with applicable accruals and in the ordinary course of business. The accounts of all participants and beneficiaries in the 401(k) Plan as of the effective time will become fully vested upon termination of the 401(k) Plan. As soon as practicable following the effective time of the merger, ESB will, at each employee’s option, either distribute the account balances to participants or transfer the balances to an eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct. WesBanco has agreed to permit ESB employees who become WesBanco employees following completion of the merger to rollover their account balances to WesBanco’s KSOP.

Dividend Reinvestment Plan. Pursuant to the terms of the merger agreement, ESB suspended the acceptance of dividends and other contributions of participants in its Dividend Reinvestment Plan (“DRIP”) as of October 31, 2014. In addition, on November 7, 2014, ESB terminated its DRIP and all ESB shares formerly held in the DRIP were withdrawn and are being held in book position for each DRIP participant’s account.

Severance and Benefits for Terminated ESB Employees. Employees of ESB (other than employees who are otherwise parties to employment, severance or change in control agreements) (i) who are not offered the opportunity to continue as employees of WesBanco or WesBanco Bank after the merger or (ii) who are terminated without cause within one year after the merger, will be entitled to receive (A) severance compensation based on the number of years of service with ESB and the employees’ weekly rate of pay, subject to certain minimum and maximum amounts, (B) accrued benefits, including vacation pay, through the date of separation, and (C) any rights to continuation of medical coverage to the extent such rights are required under applicable federal or state law and subject to the employee’s compliance with all applicable requirements for such continuation coverage, including payment of all premiums or other expenses related to such coverage.

Outplacement Services for ESB Employees. After the effective time of the merger, employees of ESB and its subsidiaries who are part of any reduction in force during the ninety (90) calendar days following the merger will be eligible to receive outplacement services with a cost of up to $2,000 for each such employee, with such cost to be paid by WesBanco.

Retention Bonus Pool. WesBanco will provide a retention bonus pool for the purposes of retaining the services of employees of ESB and its subsidiaries who are key employees through the end of the month following the conversion of the data processing system of ESB. ESB’s Chief Executive Officer shall determine, subject to approval by WesBanco’s President and Chief Executive Officer, the ESB employees eligible to receive retention awards from the retention bonus pool and any criteria for payment, and shall determine the final allocation of payments from the retention bonus pool.

Other Benefit Arrangements. As of the effective time of the merger, WesBanco will honor and assume the separation agreements, employment agreements, non-competition agreements, consulting agreements and change in control agreements in effect with the senior officers of ESB and ESB Bank.

Treatment of ESB Stock Options

Options issued by ESB to employees and directors to purchase an aggregate of [—] shares of ESB common stock were outstanding as of the ESB record date. Upon completion of the merger, each outstanding option to purchase shares of ESB common stock, whether or not then exercisable, will be cancelled in exchange for the right to receive an amount in cash, without interest, equal to the product of (i) the aggregate number of shares of ESB common stock subject to such stock option, multiplied by (ii) the excess, if any, of $17.65 over the per share exercise price of such ESB stock option. The cash payment will be subject to applicable tax withholding.

Treatment of ESB Restricted Stock

ESB shall take all actions necessary to ensure that, at or prior to the effective time of the merger, each restricted share of ESB commons stock becomes vested and no longer subject to restrictions, and as a result at the effective time of the merger shall be unrestricted shares of ESB common stock and shall receive the merger consideration.

Background of the Merger

From time to time over the past several years, ESB’s board of directors has periodically discussed and reviewed ESB’s business, performance and prospects and has considered various strategic alternatives. In the context of such reviews, the strategic alternatives considered by ESB’s board of directors have included continuing its on-going operations as an independent institution, acquiring other depository institutions, branch offices or other financial services firms engaged in complementary lines of business and entering into a strategic merger with a similarly sized or larger institution. The ESB board of directors also periodically reviewed, often with input from an investment banking firm, the competitive environment in ESB’s market area and merger and acquisition activity in the financial services industry in general and in the western Pennsylvania market area in particular.

During the first week of June 2014, the ESB board of directors and ESB’s senior management met in an offsite location to undertake their annual strategic review of ESB’s results of operations, business, performance and prospects. Among other things, the ESB board of directors also considered the current and prospective environment in which ESB operates, the current competitive environment for financial institutions, increased regulatory burdens and the uncertain operating climate going forward. The ESB board of directors determined that it may be prudent for it to engage the services of an investment banking firm in order to assist the board of directors in analyzing the various potential strategic alternatives available to ESB. The ESB board of directors invited Mufson Howe Hunter & Company LLC (“MHH”) and another nationally recognized investment banking firm to provide the board with an overview of the financial institution industry in ESB’s market area, its assessment of merger and acquisition activity in the region and on a nationwide basis and its assessment of potential business combination transactions that might be available to ESB. Each of the firms was also asked to address such firm’s qualifications and abilities to assist the board of directors in analyzing ESB’s strategic options, including a possible merger or strategic combination with another institution.

After considering the presentations made at its June 2014 strategic review, ESB’s board of directors determined that it would be in ESB’s best interest to commence a process to identify potential business combination transactions that might be available to ESB. In addition, after considering the qualifications and experience of the two investment banking firms, including the presentation that each firm made to the board and the proposed terms of engagement of each firm, the ESB board of directors decided to retain MHH to assist ESB. The ESB board then directed MHH to solicit indications of interest from parties to be identified by MHH as potentially having a reasonable interest in engaging in a business combination transaction with ESB. On June 4, 2014, ESB and MHH executed an engagement letter pursuant to which MHH was retained as ESB’s exclusive financial advisor and investment banker in connection with any business combination transaction that ESB might determine to pursue.

From mid-June through the end of July, MHH worked with senior management of ESB to prepare confidential marketing materials and to establish an electronic data room that could be accessed by interested parties who executed confidentiality agreements. During this time, MHH, in consultation with ESB, also developed a list of parties who were believed to have a potential interest in a business combination transaction with ESB. The list of potential interested parties, which was created by MHH with input from senior management at ESB, was comprised of 12 institutions, all of which were bank or savings and loan holding companies, that MHH believed, based on its experience and information available, might be interested in entering into a transaction with ESB.

WesBanco’s Chairman, James Gardill, and its recently retired President, Paul Limbert, have been business acquaintances of ESB’s President and CEO, Charlotte Zuschlag, for a number of years. Messrs. Gardill and Limbert introduced Ms. Zuschlag to Todd Clossin, who had been designated as Mr. Limbert’s successor, in January 2014. The four also met for dinner in August 2014 and discussed the general business climate in the region, among other matters. The two companies also have had business dealings over the years and ESB is a current loan customer of WesBanco.

On August 4, 2014, ESB’s board of directors reviewed the confidential marketing materials prepared by MHH and discussed with MHH the list of 12 potential interested parties that had been developed. The board of directors authorized MHH to commence a process of contacting the 12 potential business combination partners that had been identified in order to assess their level of interest in discussing a possible transaction with ESB. During the weeks of August 4 and August 11, 2014, MHH contacted the 12 institutions on behalf of ESB. As a result of MHH’s inquiries, 10 of the institutions contacted, including WesBanco, executed non-disclosure agreements (“NDAs”) and received information relating to ESB’s operations and financial performance. Two of the 12 institutions initially contacted by MHH indicated that they had no interest in pursuing a transaction or in receiving an NDA. Of the 10 institutions that executed NDAs, five institutions indicated that they were not interested in pursuing a business combination transaction after they had reviewed information provided by MHH on ESB’s behalf.

WesBanco received a call from MHH on August 7^th followed by a formal NDA later that day which it executed and returned. WesBanco then contacted FBRC and subsequently engaged FBRC as its financial advisor in connection with a potential business combination involving ESB pursuant to an engagement agreement with FBRC dated August 14, 2014. In selecting FBRC, WesBanco considered FBRC’s experience and reputation and FBRC’s knowledge of WesBanco and its industry. At its regular meeting on August 20^th the Executive Committee of WesBanco reviewed and discussed certain preliminary information and financial analysis concerning the potential transaction with ESB. Subsequently, on August 28^th, at its regularly scheduled bi-monthly meeting, management made a presentation to the full board of directors of WesBanco based on the results of the preliminary due diligence from the information available in the electronic data room. The WesBanco board of directors authorized management to submit a non-binding indication of interest to acquire ESB.

On September 5^th and 6^th, 2014, each of the five remaining parties that had signed NDAs, including WesBanco, submitted non-binding indications of interest to acquire ESB. WesBanco’s initial indication of interest proposed a transaction consisting of 80% of WesBanco common stock with a fixed exchange ratio and 20% cash, with an implied value to be within a range of $16.50 to $17.00 per share of ESB common stock, or approximately $302.4 million to $312.0 million in the aggregate. Two other institutions (“Company B” and “Company C”) submitted initial indications of interest for proposed transactions with implied values in a range of $16.00 to $17.00 per ESB share. The two other institutions that submitted initial indications of interest (“Company D” and “Company E”) proposed transactions with an implied value of less than $16.00 per share of ESB common stock.

The ESB board of directors met on September 9, 2014 to consider the five non-binding indications of interest that had been received. Upon such review, the ESB board of directors determined to continue discussions with WesBanco as well as Companies B and C and to permit each of them to conduct additional due diligence, including a review of various ESB materials that were requested by the three institutions, including information on ESB’s loan portfolio, securities portfolio and other materials. Companies D and E were advised that, based on their initial indications of interest, they were not being invited to continue in the process.

At its regularly monthly meeting held on September 17, 2014, WesBanco’s Executive Committee of its board of directors received an update on the status of the bid process and potential price range with ESB and were informed that WesBanco would pursue additional due diligence on September 18 and 19, 2014 in Pittsburgh.

On September 18^th and 19^th, 2014, representatives of WesBanco conducted their review of ESB’s materials at an off-site due diligence session and met with senior management of ESB. The following week, September 22 through 26, 2014, representatives of each of Company B and Company C conducted their off-site due diligence review is of ESB’s materials and met with senior management of ESB. Each of the three parties provided revised indications of interest on October 2, 2014, as had been requested by MHH on ESB’s behalf.

- 49 -

ESB’s board of directors met on October 6, 2014 to consider the revised indications of interest submitted by each of WesBanco, Company B and Company C. Representatives of MHH and Silver, Freedman, Taff & Tiernan LLP, ESB’s outside legal counsel, participated in the board meeting. MHH reviewed with ESB’s board of directors the process that had been undertaken to date and then reviewed in detail the revised indications of interest that had been received from each of WesBanco and Companies B and C, and reviewed with the board an overview of each of the parties that submitted revised indications of interest on a stand-alone as well as a pro-forma basis when combined with ESB. WesBanco’s revised indication of interest reflected a proposed transaction consisting of 85% WesBanco common stock, with a fixed exchange ratio, and 15% cash, with an implied value of $17.65 per share of ESB common stock. MHH advised the ESB board of directors that WesBanco was considering increasing the stock component to 90% of the merger consideration. The revised indication of interest submitted by WesBanco had an implied value per share to ESB shareholders that was higher than the other two revised indications of interest. Members of the ESB board of directors asked various questions of MHH and ESB’s legal counsel. Based on its review of the three revised indications of interest, the results of the process conducted by MHH on ESB’s behalf, and the potential benefits and risks of a merger of ESB with and into WesBanco, the ESB board of directors determined to continue its discussions solely with WesBanco and to request that WesBanco have its counsel prepare and deliver a draft definitive merger agreement to ESB and its legal counsel. The ESB board of directors also determined that it was advisable for representatives of ESB to conduct a further due diligence review of WesBanco.

On October 7, 2014, Philips, Gardill, Kaiser & Altmeyer, PLLC, provided an initial draft of the merger agreement to Silver, Freedman Taff & Tiernan LLP, counsel to ESB. Silver, Freedman, Taff & Tiernan LLP reviewed the daft of merger agreement with both ESB and representatives of MHH and provided comments on the draft merger agreement to Philips, Gardill, Kaiser and Altmeyer, PLLC, and K&L Gates LLP, securities counsel to WesBanco. From October 10, 2014 through October 29, 2014, WesBanco and ESB, with the assistance of their respective legal counsel and financial advisors, continued to negotiate the terms of the definitive merger agreement and related documents. In addition, WesBanco and ESB, with the assistance of their respective legal counsel and financial advisors, continued to discuss various matters related to the proposed combination of WesBanco and ESB.

At its regular monthly meeting held on October 15, 2014, WesBanco’s Executive Committee of its board of directors received an update on the status of the discussions and the selection by ESB of WesBanco as its preferred partner. The Executive Committee also received an update on the status of the negotiation of a definitive merger agreement and the principal issues regarding the terms and conditions of such an agreement. The Executive Committee reviewed and discussed updated pro forma financial projections concerning the proposed transaction prepared by WesBanco management. The Executive Committee reviewed and discussed preliminary financial analysis with respect to ESB, WesBanco, and the proposed merger.

On October 16, 2014, representatives of ESB, MHH and ESB’s legal counsel were provided access to, and reviewed, certain non-public information regarding WesBanco. Representatives of ESB, MHH and ESB’s legal counsel met with representatives of WesBanco’s management on October 16, 2014 to discuss WesBanco’s business, results of operations and prospects and to review various documents on-site at WesBanco’s offices.

The WesBanco board of directors met on October 22 and October 23, 2014 at its regular bi-monthly meetings. During these regular bi-monthly meetings, the WesBanco board of directors also reviewed and discussed the proposed transaction. The meeting began on the afternoon of October 22 at which meeting Mr. Gardill, as outside counsel for WesBanco, presented each member of the board of directors with a copy of the definitive agreement and plan of merger for their review and consideration. The following morning the board met again to discuss the proposed transaction. Representatives of Philips, Gardill, Kaiser and Altmeyer, PLLC advised the board of directors that pursuant to the merger agreement, (i) each share of ESB common stock, par value $.01 per share, outstanding immediately prior to the merger, other than certain shares specified in the merger agreement, will, without any action on the part of the holder thereof, be converted into and represent the right to receive upon consummation of the merger (a) $1.76 in cash, and (b) 0.5020 of a share of WesBanco common stock, par value $2.0833 per share, subject to adjustment, and (ii) each option to purchase a share of

- 50 -

ESB common stock outstanding immediately prior to the merger will, without any action on the part of the holder thereof, be converted into and represent the right to receive upon consummation of the merger an amount in cash equal to the product of (a) the aggregate number of shares of ESB common stock subject to such option, multiplied by (b) the excess, if any, of $17.65 over the per share exercise price of such option. In addition, various members of management provided input concerning the presentation. At the request of the WesBanco board of directors, FBRC then reviewed and discussed its preliminary financial analyses with respect to WesBanco, ESB and the proposed merger and reviewed with the WesBanco board of directors a preliminary draft of its opinion as to the fairness, from a financial point of view, to WesBanco of the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement.

Subsequently, on October 29, 2014, a telephonic meeting of the board of directors of WesBanco was conducted with representatives of K&L Gates, corporate securities counsel for WesBanco, and FBR in attendance at the request of the board of directors. FBRC reviewed and discussed its financial analyses with respect to the WesBanco, ESB and the proposed merger. Thereafter, at the request of the WesBanco board of directors, FBRC rendered its oral opinion to the WesBanco board of directors (which was subsequently confirmed in writing by delivery of FBRC’s written opinion dated October 29, 2014) to the effect that, subject to the qualifications and limitations and other matters considered in connection with the preparation of FBRC’s opinion, as of October 29, 2014, the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement was fair, from a financial point of view, to WesBanco. The board also received a recommendation from management to proceed with the execution of the definitive agreement and plan of merger with ESB.

During the afternoon of October 29, 2014, the boards of directors of ESB and ESB Bank met in order to review the proposed merger agreement, the transactions contemplated thereby, including the merger, the terms of the merger agreement, including the merger consideration of 0.502 shares of WesBanco common stock plus $1.76 in cash to be received for each share of ESB common stock upon consummation of the merger, and the various related agreements contemplated by the merger agreement. The ESB and the ESB Bank boards received presentations regarding the proposed merger agreement from ESB’s financial advisor, MHH, and from its legal counsel, Silver, Freedman, Taff & Tiernan LLP. Legal counsel, MHH and senior management of ESB also briefed the boards on the results of the due diligence review conducted on WesBanco. Representatives of MHH and legal counsel responded to questions from the directors. At the meeting, MHH presented its opinion that the merger consideration to be received by shareholders of ESB was fair to ESB’s shareholders from a financial point of view. After careful and deliberate consideration of the presentations by ESB’s financial advisor and legal counsel as well as the interests of ESB’s shareholders, customers, employees and the communities served by ESB, the board of directors of ESB unanimously approved the merger agreement and the related documents. The board of directors of ESB Bank also unanimously approved the merger agreement and the related documents.

Following the meeting of ESB’s board of directors on October 29, 2014, the merger agreement and related documents were executed and the parties issued a press release announcing the proposed merger after the close of market trading.

WesBanco’s Reasons for the Merger

After careful consideration, WesBanco’s board of directors determined that the merger is in the best interests of WesBanco and its shareholders. WesBanco’s board of directors therefore unanimously recommends that the WesBanco shareholders’ vote “For”: (i) approval of the issuance of shares of WesBanco common stock in connection with the merger; and (ii) approval of an adjournment of the WesBanco special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the issuance of shares of WesBanco common stock in connection with the merger at the time of the WesBanco special meeting.

In reaching the determination to approve the merger, the merger agreement and the related issuance of shares to consummate the merger, WesBanco’s board of directors consulted with WesBanco’s senior management, financial advisor and legal advisors, and drew on its knowledge of the business, operations,

- 51 -

properties, assets, financial condition, operating results, historical market prices, and prospects of ESB and WesBanco, as well as current economic and market conditions. In connection with its review and approval of the merger, the merger agreement and the issuance of shares to consummate the merger, and in the course of its deliberations, WesBanco’s board of directors considered numerous factors that weighed in favor of the merger, including the following:

• Merger Consideration. WesBanco’s board of directors considered in its financial analysis the implied price per share for selected companies and transactions analysis utilizing the 25^th and 75^th percentiles of pricing multiples to determine an implied price per share range based on pricing as of October 27, 2014. In considering that range, the implied consideration per share for ESB Common Stock offered by WesBanco in the transaction of $17.65 per share was at the upper end of the price to book value range of 1.43 to 2.04, was below the midpoint range of the price to long-term multiple earnings per share of 15.0 to 23.1 and was at the lower end of the DCF with cost savings and synergies with a range of 10.3 to 12.3 percent discount rate and a range of 12 to 14 times the earnings per share terminal multiple.

• ESB’s Location in the Attractive Pittsburgh Commercial Market. The WesBanco board of directors reviewed certain market and economic indicators for the Pittsburgh commercial market and compared the strength of the Pittsburgh metropolitan statistical area (“MSA”) commercial market to the Pennsylvania MSA average and the national MSA average which demonstrated the strength of the commercial market. It also considered the projected median household income five-year compound annual growth rate which showed Pittsburgh as one of the highest in the country. It also reviewed the home price index change since the first quarter of 2009 indicating that Pittsburgh was in the top three and that its retail commercial real estate vacancy rate was one of the lowest in the country. It also noted that upon completion of the acquisition, the Pittsburgh commercial market and Western Pennsylvania would comprise almost 30% of the WesBanco’s franchise measured by loans and deposits.

• Improvement in Market Share. The WesBanco board of directors also considered that the transaction would improve WesBanco’s deposit market share in the Pittsburgh MSA from its current position of 13^th to the top 10 based on pro forma deposits post acquisition of ESB.

• Leverage of Fidelity Acquisition. The WesBanco board of directors noted that the acquisition of ESB would leverage and build upon WesBanco’s prior acquisition of Fidelity Bancorp, Inc. in the Pittsburgh market through greater penetration in the market with an existing highly experienced Pittsburgh market management team and commercial lending group. The transaction would permit WesBanco to operate a significantly enhanced franchise in both the number of branches and in total assets utilizing its existing management team.

• Limited Market Opportunity. ESB also represents the last standing sizeable franchise left in the attractive Pittsburgh MSA market with desirable branch locations. The WesBanco board of directors noted that ESB had been voted as a top ten performing thrift for 2013 by SNL and there were limited other options to expand WesBanco’s market share in the Pittsburgh MSA and Western Pennsylvania markets.

• Limited Integration Risk. Given its geographic proximity to WesBanco’s headquarters, the similar disciplined risk cultures and customer focus of ESB and its high performance standards and management leadership, there was limited risk in completing the integration successfully compared to other options and alternatives available to WesBanco on the M&A side. Additionally, given WesBanco’s prior successes in converting thrift-like organizations the WesBanco board of directors considered there was a high degree of probability of a successful integration in this transaction.

• Strong Financial Motivations. The WesBanco board of directors also considered the substantial accretion to earnings per share that would result from the transaction including estimated double digit return in the years 2016 and beyond. The WesBanco board of directors also noted the high internal rate of return which was projected to be in the high teens. The board noted the tangible book value dilution, with restructuring charges but considered that the earnings per share accretion strength would permit

- 52 -

the earn back in 2.4 years using the incremental retained earnings method and in 5.4 years using the cross over method while reflecting all merger related expenses, purchase accounting adjustments and cost saves.

• Retention of Well Capitalized Status. The WesBanco board of directors also reviewed the pro forma financial information and noted that WesBanco would remain well in excess of the “well capitalized” guidelines for regulatory purposes on a pro forma basis.

• Opinion and Analysis of the Financial Advisor to WesBanco. WesBanco’s board of directors considered the financial analysis reviewed and discussed with the WesBanco board of directors by representatives of FBRC as well as the oral opinion of FBRC rendered to the WesBanco board of directors on October 29, 2014 (which was subsequently confirmed in writing by delivery of FBRC’s written opinion addressed to the WesBanco board of directors dated the same date) as to, as of October 29, 2014, the fairness, from a financial point of view, to WesBanco of the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement.

• Merger Agreement Terms and Conditions. The Wesbanco board of directors reviewed with independent outside counsel the terms and conditions of the merger agreement and determined that the terms and conditions were reasonable and necessary to consummate the transaction and provided sufficient safeguards pending shareholder and regulatory approvals that would preserve the franchise value of ESB during the interim period from the date of execution of the agreement to the closing of the transaction and the completion of the integration of ESB.

• Adverse Impact of Section 280G Issues. The Wesbanco board of directors also reviewed with outside counsel the potential income tax consequences of the gross up language of the various employment contracts and change in control agreements between ESB and certain of its named executive officers and concluded that the new employment contracts, non-competition agreements, change in control agreements and consulting agreement entered into by such officers in connection with the merger substantially mitigated any risk of adverse tax consequences arising by reason of Section 280G of the Internal Revenue Code (see the discussion under the heading “— Interests of Certain Persons in the Merger” beginning on page [—] for more information about these agreements).

The reasons set forth above are not intended to be exhaustive, but include the material considerations of WesBanco’s board of directors in approving the merger agreement. In reaching the determination to approve and recommend the transaction, WesBanco’s board of directors looked at the totality of the information presented to it and did not assign any relative or specific weights to the factors considered, and individual directors may have given different weights to different factors. After considering, among other things, the matters discussed above, WesBanco’s board of directors believed that the merger consideration was fair to WesBanco and its shareholders and therefore unanimously approved and recommends that the WesBanco’s shareholders vote “For” approval of: (i) the issuance of shares of WesBanco common stock in connection with the merger and (ii) the adjournment of the WesBanco special meeting, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the WesBanco special meeting to approve the proposal to approve the issuance of WesBanco common stock in connection with the merger.

Opinion of WesBanco’s Financial Advisor

On October 29, 2014, FBRC rendered its oral opinion to the WesBanco board of directors (which was subsequently confirmed in writing by delivery of FBRC’s written opinion addressed to the WesBanco board of directors dated the same date), to the effect that, as of October 29, 2014, the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement was fair, from a financial point of view, to WesBanco.

FBRC’s opinion was directed to the WesBanco board of directors (in its capacity as such), and only addressed the fairness, from a financial point of view, to WesBanco of the consideration to be issued and

- 53 -

paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement and did not address any other aspect or implication of the transaction. The summary of FBRC’s opinion in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of FBRC’s written opinion, which is included as Annex B to this joint proxy statement/prospectus and sets forth the procedures followed, assumptions made, qualifications and limitations on the review undertaken and other matters considered by FBRC in preparing its opinion. However, neither FBRC’s written opinion nor the summary of its opinion and the related analyses set forth in this joint proxy statement/prospectus are intended to be, and they do not constitute, advice or a recommendation to the WesBanco board of directors, WesBanco, WesBanco Bank, any securityholder of WesBanco or any other person as to how to act or vote on any matter relating to the transaction or otherwise.

In arriving at its opinion, FBRC, made such reviews, analyses and inquiries as FBRC deemed necessary and appropriate under the circumstances. Among other things, FBRC:

• reviewed an execution version of the merger agreement;

• reviewed certain publicly available business and financial information relating to ESB and WesBanco;

• reviewed certain other business, financial and operating information relating to ESB, including financial forecasts for ESB for the fiscal years ending December 31, 2014 through December 31, 2016 prepared and provided to FBRC by management of ESB (the “ESB Projections”), as adjusted and extended by the management of WesBanco through the fiscal year ending December 31, 2019, to take into account certain cost savings and synergies expected by the management of WesBanco to result from the transaction and WesBanco’s ownership, control and operation of ESB and ESB Bank following the consummation of the merger (the “WesBanco Projections for ESB”);

• reviewed certain other business, financial and operating information relating to WesBanco, including publicly available research analyst estimates for WesBanco for the fiscal years ending December 31, 2014 and December 31, 2015 and financial forecasts for WesBanco for the fiscal years ending December 31, 2016 through December 31, 2019 prepared and provided to FBRC by management of WesBanco (the “WesBanco Projections”);

• met with certain members of the managements of ESB and WesBanco to discuss the business and prospects of ESB and WesBanco and the proposed transaction;

• reviewed certain financial data for ESB and WesBanco and compared that data with similar data for companies with publicly traded equity securities that FBRC deemed relevant;

• reviewed certain financial terms of the proposed merger and compared certain of those terms with the publicly available financial terms of certain business combinations and other transactions that FBRC deemed relevant; and

• considered such other information, financial studies, analyses and investigations and financial, economic and market criteria that FBRC deemed relevant.

As WesBanco was aware, FBRC relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to it, discussed with or reviewed by it, or publicly available, and did not assume any responsibility with respect to such data, material and other information. With respect to the ESB Projections, management of ESB advised FBRC, and FBRC assumed, that the ESB Projections were reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of the management of ESB with respect to the future financial performance of ESB. With respect to the WesBanco Projections for ESB, management of WesBanco advised FBRC, and FBRC assumed, that the WesBanco Projections for ESB were reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of the management of WesBanco with respect to the future financial performance of ESB following the consummation of the transaction, after giving

- 54 -

effect to the cost savings and synergies expected by WesBanco management to result from the transaction and WesBanco’s ownership, control and operation of ESB and ESB Bank after giving effect to the transaction. With respect to the WesBanco Projections, management of WesBanco advised FBRC, and FBRC assumed, that the WesBanco Projections were reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of the management of WesBanco with respect to the future financial performance of WesBanco. FBRC relied without independent verification upon the assessment of the management of WesBanco with respect to the timing and risks associated with the integration of the businesses of WesBanco and ESB and the risks associated with WesBanco’s and ESB’s current and contemplated products, services and business models. FBRC expressed no view or opinion with respect to the ESB Projections, the WesBanco Projections for ESB, the WesBanco Projections or the assumptions on which they were based including, without limitation, the cost savings and synergies expected by WesBanco management to result from the transaction, which cost savings and synergies FBRC, at WesBanco’s direction, assumed would be achieved in the amounts and at the times indicated thereby. WesBanco advised FBRC and FBRC assumed without undertaking any responsibility for the independent verification thereof, that the WesBanco Projections for ESB, the WesBanco Projections and the assumptions on which they were based were a reasonable basis on which to evaluate ESB, WesBanco and the proposed transaction and, at WesBanco’s direction, FBRC used and relied upon the WesBanco Projections for ESB and the WesBanco Projections for purposes of its analyses and opinion. FBRC also relied upon and assumed, without independent verification, that there had been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of ESB or WesBanco since the dates of the most recent financial statements and other information, financial or otherwise, provided to FBRC that would be material to its analyses or opinion, and that there was no information or any facts or developments that would make any of the information reviewed by FBRC incomplete or misleading. FBRC also assumed, with WesBanco’s consent, that (i) in the course of obtaining any regulatory or third party consents, approvals or agreements in connection with the transaction, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on ESB, WesBanco or the contemplated benefits of the transaction; (ii) the representations and warranties made by the parties in the merger agreement were accurate and complete in all respects material to FBRC’s analyses and opinion; (iii) each party to the merger agreement would perform all of its covenants and obligations thereunder; (iv) the transaction would be consummated in accordance with the terms of the merger agreement, without waiver, modification or amendment of any term, condition or provision thereof material to FBRC’s analyses or opinion; and (v) that the transaction would together qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. FBRC also assumed that the merger agreement, when executed by the parties thereto, would conform to the execution version reviewed by FBRC in all respects material to its analyses.

FBRC’s opinion only addressed the fairness, from a financial point of view, to WesBanco of the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger pursuant to the merger agreement and did not address any other aspect or implication of the transaction or any agreement, arrangement or understanding entered into in connection therewith or otherwise, including, without limitation, the form or, except to the extent expressly provided in the opinion, the amounts of the consideration to be issued and paid in the merger; the allocation of the outstanding shares of WesBanco common stock after giving effect to the transaction as between the current holders of WesBanco common stock and the current holders of ESB common stock or any individual members or groups thereof; the dilutive or other effects of the transaction on the existing holders of WesBanco common stock; the solvency or fair value of WesBanco, ESB or any other entity or person or their respective assets or liabilities under any laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters; any tax implications of the transaction to WesBanco or its security holders or any other party; the fairness of any portion or aspect of the transaction to the current holders of any class of securities, creditors or other constituencies of WesBanco, ESB or to any other party; or the fairness of the amount or nature of, or any other aspect relating to, any compensation or consideration to be received by or otherwise payable to any officers, directors, employees, securityholders or affiliates of any party to the transaction, or class of such persons, relative to the consideration to be issued and paid by WesBanco in respect of the outstanding shares of ESB common stock in the merger or otherwise. The issuance of FRBC’s opinion was approved by an authorized internal committee of FBRC.

- 55 -

FBRC did not express any opinion or provide any advice, counsel or interpretation, with respect to matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. FBRC assumed that any such opinions, advice, counsel or interpretations had been or would be obtained by WesBanco from appropriate professional sources. Furthermore, FBRC, with WesBanco’s consent, relied upon the assessments by WesBanco and its other advisors as to all legal, regulatory, accounting, insurance and tax matters with respect to WesBanco, ESB and the transaction.

FBRC’s opinion was necessarily based upon information made available to FBRC as of the date of the opinion and financial, economic, market and other conditions as they existed and could be evaluated on the date of the opinion. Although subsequent developments could affect its opinion, FBRC does not have any obligation to update, revise or reaffirm its opinion. As WesBanco was aware, the credit, financial and stock markets experienced significant volatility and FBRC expressed no opinion or view as to any potential effects of such volatility on WesBanco, WesBanco Bank, ESB, ESB Bank or the transaction. FBRC’s opinion did not address the relative merits of the transaction as compared to alternative transactions or strategies that might be available to WesBanco, WesBanco Bank, ESB, ESB Bank or any other party to the transaction, nor did it address the underlying business decision of the WesBanco board of directors, WesBanco, WesBanco Bank, ESB, ESB Bank or any other party to proceed with the transaction. Furthermore, in connection with its opinion, FBRC was not requested to, and did not, make any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (contingent or otherwise) of WesBanco, WesBanco Bank, ESB, ESB Bank or any other party, nor was FBRC provided with any such appraisal or evaluation. In addition, FBRC did not receive or review any individual credit files nor did FBRC make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of WesBanco, WesBanco Bank, ESB, ESB Bank or any of their respective subsidiaries and FBRC was not furnished with any such evaluations or appraisals. FBRC is not an expert in the evaluation of loan, lease, investment or trading portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto and, accordingly, FBRC assumed that such allowances for losses were adequate to cover such losses. FBRC did not express any opinion as to what the value of shares of WesBanco common stock actually would be when issued pursuant to the merger, or the price or range of prices at which WesBanco common stock or ESB common stock could be purchased or sold at any time. With WesBanco’s consent, FBRC assumed that the shares of WesBanco common stock to be issued in the merger would be listed on the NASDAQ Global Select Market.

FBRC’s opinion was for the information of the WesBanco board of directors (in its capacity as such) in connection with its consideration of the proposed merger. The opinion was not intended to and should not be construed as creating any fiduciary duty on the part of FBRC to the WesBanco board of directors, WesBanco, WesBanco Bank any security holder of WesBanco or any other party. FBRC’s opinion did not constitute a recommendation to the WesBanco board of directors, WesBanco, WesBanco Bank any securityholder of WesBanco or any other person as to how to act or vote on any matter relating to the transaction or otherwise.

In preparing its opinion to the WesBanco board of directors, FBRC performed a variety of analyses, including those described below. The summary of FBRC’s financial analyses is not a complete description of the analyses underlying FBRC’s opinion. The preparation of such an opinion is a complex process involving various quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytic methods employed and the adaptation and application of those methods to the unique facts and circumstances presented. As a consequence, neither FBRC’s opinion nor the analyses underlying its opinion are readily susceptible to partial analysis or summary description. FBRC arrived at its opinion based on the results of all analyses undertaken by it and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any individual analysis, analytic method or factor. Accordingly, FBRC believes that its analyses must be considered as a whole and that selecting portions of its analyses, analytic methods and factors, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying its analyses and opinion.

In performing its analyses, FBRC considered business, economic, industry and market conditions, financial and otherwise, and other matters as they existed on, and could be evaluated as of, the date of its opinion. No

company, business or transaction used in FBRC’s financial analyses for comparative purposes is identical to WesBanco, ESB or the proposed transaction. While the results of each analysis were taken into account in reaching its overall conclusion, FBRC did not make separate or quantifiable judgments regarding individual analyses. The multiples and valuation reference ranges indicated by FBRC’s financial analyses are illustrative and not necessarily indicative of actual values nor predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold, which may depend on a variety of factors, many of which are beyond WesBanco’s control and the control of FBRC. Much of the information used in, and accordingly the results of, FBRC’s analyses are inherently subject to substantial uncertainty.

FBRC’s opinion and analyses were provided to the WesBanco board of directors (in its capacity as such) in connection with its consideration of the proposed transaction and were among many factors considered by the WesBanco board of directors in evaluating the proposed transaction. Neither FBRC’s opinion nor its analyses were determinative of the consideration or of the views of the WesBanco board of directors with respect to the proposed transaction.

The following is a summary of the material financial analyses performed by FBRC in connection with the preparation of its opinion rendered to the WesBanco board on October 29, 2014. The analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the analyses. Considering the data in the tables below without considering the full narrative description of the analyses, as well as the methodologies underlying, and the assumptions, qualifications and limitations affecting, each analysis, could create a misleading or incomplete view of FBRC’s analyses.

Unless the context indicates otherwise, (1) share prices for the selected companies used in the selected companies analysis described below were as of October 27, 2014, (2) estimates of financial performance of ESB and WesBanco were based on the WesBanco Projections for ESB and the WesBanco Projections, respectively, (3) estimates of financial performance for the selected companies listed below for the next fiscal year were based on publicly available research analyst estimates for those companies, and (4) the transaction values per share for the selected transactions used in the selected transactions analysis described below were based on the value of the consideration proposed to be paid in the selected transactions as of the date of the announcement.

Based on the merger consideration per ESB share of $1.76 in cash and 0.502 of a share of WesBanco common stock, FBRC calculated an implied value of the merger consideration of $17.65 per share of ESB common stock, by adding $1.76 to the product of 0.502 and $31.66, the average closing price per share of WesBanco common stock for the 15-trading day period ending on October 27, 2014.

Taking into account the results of the selected transactions analysis for ESB, FBRC applied multiple ranges based on the 25^th to 75^th percentiles of Price/TBV and Price/LTM EPS to corresponding financial data for ESB. The selected transactions analysis indicated implied valuation reference ranges per share of ESB common stock of $13.24 to $18.92 based on the Price/TBV multiples and $14.74 to $22.61 based on the Price/LTM EPS multiples, as compared to the implied value of the merger consideration of $17.65 per share of ESB common stock.

Discounted Cash Flow Analysis

FBRC performed a discounted cash flow analysis of ESB based on the WesBanco Projections for ESB, with and without taking into account the cost savings and synergies expected by the management of WesBanco to result from the transaction and WesBanco’s ownership, control and operation of ESB and ESB Bank following the consummation of the transaction. FBRC applied a range of terminal value multiples of 12.0x to 14.0x to an estimate of ESB’s 2020 free cash flow calculated by applying a 5% growth rate to the estimated 2019 free cash flow in the WesBanco Projections for ESB, as per WesBanco management. The estimated net present value of the projected future cash flow and terminal values were then calculated using discount rates ranging from 10.3% to 12.3%. The discounted cash flow analysis indicated implied valuation reference ranges per share of ESB common stock of approximately $12.85 to $15.40, without taking into account the cost savings and synergies expected by the management of WesBanco to result from the transaction and WesBanco’s ownership, control and operation of ESB and ESB Bank following the consummation of the transaction, and $16.80 to $21.18, taking into taking into account the cost savings and synergies expected by the management of WesBanco to result from the transaction and WesBanco’s ownership, control and operation of ESB and ESB Bank following the consummation of the transaction, as compared to the implied value of the merger consideration of $17.65 per share of ESB common stock.

Other Matters

WesBanco selected FBRC as its financial advisor in connection with the proposed merger based on FBRC’s experience and reputation and FBRC’s knowledge of WesBanco and its industry. FBRC will receive a transaction fee of $1,750,000 for its services as financial advisor to WesBanco in connection with the merger, which is contingent upon the successful completion of the merger. FBRC will also receive a fee of $250,000 for rendering its opinion, which is not contingent upon the successful completion of the merger. In addition, WesBanco has also agreed to indemnify FBRC and certain related parties for certain liabilities arising out of or related to FBRC’s engagement and to reimburse FBRC for certain expenses incurred in connection with its engagement.

FBRC is a full service securities firm engaged in securities trading and brokerage activities as well as providing investment banking and other financial services. In the ordinary course of business, FBRC and its affiliates may acquire, hold or sell, for its and its affiliates own accounts and the accounts of customers, equity, debt and other securities and financial instruments (including bank loans and other obligations) of WesBanco, ESB, certain of their affiliates and any other company that may be involved in the transaction. FBRC and its affiliates may in the future provide investment banking and other financial services to WesBanco, ESB and certain of their respective affiliates, for which FBRC and its affiliates would expect to receive compensation. FBRC has adopted policies and procedures designed to preserve the independence of its research and credit analysts whose views may differ from those of the members of the team of investment banking professionals that are advising WesBanco.

ESB’s Reasons for the Merger

After careful consideration, the ESB board of directors determined that it was advisable and in the best interests of ESB and its shareholders for ESB to enter into the merger agreement with WesBanco. Accordingly, ESB’s board unanimously recommends that ESB’s shareholders vote “FOR” the adoption of the merger agreement.

The board of directors of ESB has considered the terms and provisions of the merger agreement and concluded that they are fair to the shareholders of ESB and that the merger is in the best interests of ESB and its shareholders.

In reaching its decision to approve the merger agreement, the ESB board of directors consulted with management, as well as with ESB’s financial and legal advisors, and considered a variety of factors, including the following:

• The consideration being offered to ESB’s shareholders in relation to the market price, book value per share, earnings per share and projected earnings per share of ESB;

• The results that could be expected to be obtained by ESB if it continued to operate independently and the potential future trading value of ESB common stock compared to the value of the merger consideration offered by WesBanco and the potential future trading value of the WesBanco common stock;

• The limited prospects for ESB to grow its franchise through additional acquisitions given the relatively limited number of acquisition prospects available to ESB in western Pennsylvania as well as the prospective level of book value dilution likely to be incurred by ESB in any acquisition of another depository institution;

- 61 -

• The process conducted by MHH, ESB’s financial advisor, to identify potential merger partners and to assist the ESB board of directors in structuring the proposed merger with WesBanco;

• The current and prospective environment in which ESB operates, including national, regional and local economic conditions, the competitive environment for financial institutions, the increased regulatory burdens on financial institutions, and the uncertainties in the regulatory climate going forward;

• The scale, scope, strength and diversity of operations, product lines and delivery systems that could be achieved by combining ESB with WesBanco;

• The complementary geographic locations of the ESB and WesBanco branch networks;

• WesBanco’s asset size and capital position, which would give the resulting institution over $8.0 billion in assets;

• The earnings prospects of the combined companies;

• The additional products offered by WesBanco to its customers and the ability of the resulting institution to provide comprehensive financial services to its customers;

• ESB’s and WesBanco’s shared community banking philosophies; and

• The presentation by MHH, ESB’s financial advisor, as to the fairness of the merger consideration, from a financial point of view, to ESB’s shareholders. In this regard, ESB’s board of directors reviewed MHH’s opinion dated October 29, 2014 that, as of such date, the merger consideration was fair to ESB’s shareholders from a financial point of view. The opinion is attached as Annex C to this document. For a summary of the presentation of MHH, see “Opinion of ESB’s Financial Advisor” below.

Other factors considered by ESB’s board of directors included:

• The reports of ESB’s management and the financial presentation by MHH to ESB’s board of directors concerning the operations, financial condition and prospects of WesBanco and the expected financial impact of the merger on the combined company, including pro forma assets, earnings, deposits and capital ratios;

• The proposed board arrangements of the combined company, including the proposed inclusion of a current director of ESB and a current director of ESB Bank on WesBanco’s board;

• The likelihood of successful integration and the successful operation of the combined company;

• The likelihood that the regulatory approvals needed to complete the transaction will be obtained;

• The potential cost-saving opportunities;

• The effects of the merger on ESB’s employees, including the prospects for continued employment and the severance and other benefits agreed to be provided to ESB employees; and

• The review by the ESB board of directors with its legal and financial advisors of the structure of the merger and the financial and other terms of the merger, including the merger consideration and the condition that the merger must qualify as a reorganization under section 368(a) of the Code, which will permit ESB’s shareholders to receive WesBanco shares, which constitutes the primary portion of the merger consideration, on a tax-free basis for federal income tax purposes.

The ESB board of directors also considered the potential risks associated with the merger in connection with its deliberation of the proposed transaction, including the challenges of integrating ESB’s businesses, operations and employees with those of WesBanco, the need to obtain approval by shareholders of both ESB and WesBanco as well as regulatory approvals in order to complete the transaction, and the risks associated with the operations

- 62 -

of the combined company including the ability to achieve the anticipated cost savings. ESB’s board also considered that the stock portion of the merger consideration was fixed at 0.502 shares of WesBanco common stock and, by its nature, would not adjust upwards to compensate for declines, or downwards to compensate for increases, in WesBanco’s stock price prior to completion of the merger. ESB’s board of directors also believed the terms and conditions of the merger agreement, including the parties’ respective representations and warranties, the conditions to closing and termination provisions, provided adequate assurances as to WesBanco’s obligation and ability to consummate the merger in a timely manner, without any extraordinary conditions.

The foregoing discussion of the information and factors considered by ESB’s board of directors is not exhaustive, but includes all material factors considered by ESB’s board. In view of the wide variety of factors considered by the ESB board of directors in connection with its evaluation of the merger and the complexity of these matters, the ESB board of directors did not consider it practical to, and did not attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered in reaching its decision. ESB’s board of directors evaluated the factors described above, including asking questions of ESB’s management and ESB’s legal and financial advisors. In considering the factors described above, individual members of ESB’s board of directors may have given different weights to different factors. The ESB board of directors relied on the experience and expertise of its financial advisors for quantitative analysis of the financial terms of the merger. See “Opinion of ESB’s Financial Advisor” below. It should also be noted that this explanation of the reasoning of ESB’s board of directors and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements” on page [—].

Opinion of ESB’s Financial Advisor

In June 2014, ESB engaged MHH to render financial advisory and investment banking services to ESB. MHH agreed to assist ESB in assessing the fairness, from a financial point of view, of the exchange ratio and cash consideration (collectively the “merger consideration”) to be received by the common shareholders of ESB pursuant to the terms of the merger agreement with WesBanco. ESB selected MHH on the basis of MHH’s experience and expertise in representing community banks in similar transactions.

As part of its engagement, representatives of MHH attended the meeting of the ESB board of directors held on October 29, 2014, at which the ESB Board of Directors evaluated the proposed merger with WesBanco. At this meeting, MHH reviewed the financial aspects of the proposed merger and rendered an opinion that, as of such date, the merger consideration was fair to ESB’s shareholders, from a financial point of view. The ESB Board approved the merger agreement at this meeting.

The full text of MHH’s written opinion is attached as Annex C to this document and is incorporated herein by reference. ESB shareholders are urged to read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by MHH. The description of the opinion set forth herein is qualified in its entirety by reference to the full text of such opinion.

MHH’s opinion speaks only as of the date of the opinion. The opinion is directed to the ESB Board and addresses only the fairness, from a financial point of view, to ESB shareholders of the merger consideration in the proposed merger. It does not address the underlying business decision to proceed with the merger and does not constitute a recommendation to any ESB shareholder as to how the shareholder should vote at the ESB special meeting on the merger or any related matter.

In rendering its opinion, MHH reviewed, among other things:

• the merger agreement;

• certain publicly available financial statements and other historical financial information of ESB that was deemed relevant;

- 63 -

• certain publicly available financial statements and other historical financial information of WesBanco that was deemed relevant;

• internal financial projections for ESB prepared by and reviewed with management of ESB;

• publicly available median earnings estimates for WesBanco for 2014 and 2015;

• the pro forma financial impact of the merger on WesBanco, based on assumptions related to transaction expenses, accounting adjustments, and cost savings determined by and discussed with senior management of WesBanco;

• publicly reported historical price and trading activity for ESB and WesBanco common stock, including a comparison of certain financial and stock market information for ESB and WesBanco with similar publicly traded companies;

• the financial terms of certain recent business combinations in the banking industry, to the extent publicly available;

• such other information, financial studies, analyses and investigations and financial, economic and market criteria as they considered relevant.

MHH also held discussions with members of senior management of ESB and WesBanco regarding their past and current business operations, regulatory relations, financial conditions, future prospects of their respective companies; and such other matters as they deemed relevant to their opinion.

In conducting its review and arriving at its opinion, MHH relied upon the accuracy and completeness of all financial and other information provided to them or otherwise publicly available. MHH did not independently verify the accuracy or completeness of any such information or assume any responsibility for such verification or accuracy. MHH relied upon the managements of ESB and WesBanco as to the reasonableness and achievability of the financial and operating forecasts and projections (and the assumptions and bases therefore) provided to MHH, and MHH assumed that such forecasts and projections reflected the best currently available estimates and judgments of such management and that such forecasts and projections will be realized in the amounts and in the time periods estimated by such managements.

MHH assumed, without independent verification, that the aggregate allowance for loan and lease losses for ESB and WesBanco are adequate to cover those losses. MHH did not make or obtain any evaluation or appraisals of the property, assets and liabilities of ESB and WesBanco, nor did it examine any individual credit files.

The projections furnished to MHH and used by it in certain of its analyses were prepared by ESB and WesBanco’s senior management teams. ESB and WesBanco do not publicly disclose internal management projections of the type provided to MHH in connection with its review of the merger. As a result, such projections were not prepared with a view towards public disclosure. The projections were based on numerous variables and assumptions, which are inherently uncertain, including factors related to general economic and competitive conditions. Accordingly, actual results could vary significantly from those set forth in the projections.

For purposes of rendering its opinion, MHH assumed that, in all respects material to its analyses:

• the merger will be completed substantially in accordance with the terms set forth in the merger agreement;

• the representations and warranties of each party in the merger agreement and in all related documents and instruments related to the merger agreement are true and correct;

• each party to the merger agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents;

- 64 -

• all conditions to the completion of the merger will be satisfied without any waivers and modifications; and

• in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the merger, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, will be imposed that will have a material adverse effect on the future results of operations or financial condition of the combined entity or the contemplated benefits of the merger, including the cost savings, revenue enhancements and related expenses expected to result from the merger.

MHH further assumed that the merger will be accounted for using the acquisition method under generally accepted accounting principles, and that the merger will qualify as a tax-free reorganization for United States federal income tax purposes. MHH’s opinion is not an expression of an opinion as to the prices at which shares of ESB common stock or shares of WesBanco common stock will trade following the announcement of the merger or actual value of the shares of common stock of the combined company when issued pursuant to the merger, or the prices at which the shares of common stock of the combined company will trade following the completion of the merger.

In performing its analyses, MHH made numerous assumptions with respect to industry performance, general business, economic, market and financial condition and other matters, which are beyond the control of MHH, ESB and WesBanco. Any estimates contained in the analyses performed by MHH are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, the MHH opinion was among several factors taken into consideration by the ESB board in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the ESB board with respect to the fairness of the merger consideration.

The following is a summary of the material analyses presented by MHH to the ESB board on October 29, 2014, in connection with its fairness opinion. The summary is not a complete description of the analyses underlying the MHH opinion or the presentation made by MHH to the ESB board, but summarizes the material analyses performed and presented in connection with such opinion. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, MHH did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. The financial analyses summarized below include information presented in tabular format. Accordingly, MHH believes that its analyses and the summary of its analyses must be considered as a whole and selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion. The tables alone do not constitute a complete description of the financial analyses.

Summary of Proposal. Pursuant to the terms of the merger agreement, each outstanding share of common stock, par value $0.01 per share, of ESB will be converted into the right to receive 0.502 of a share of common stock, par value $2.0833 per share, of WesBanco and $1.76 in cash. Based on WesBanco’s 15 day average closing price on October 27, 2014, two days before the announcement of the transaction, of $31.66, the merger consideration represented a price of $17.65 per share to ESB’s common shareholders.

Selected Comparable Companies Analyses. Using publicly available information, MHH compared the financial condition and market performance of ESB to selected publicly traded banks and thrifts headquartered in

- 65 -

Ohio, West Virginia and Pennsylvania west of Harrisburg with assets between $1 billion and $3 billion. Additionally, using publicly available information, MHH compared the financial condition and market performance of WesBanco to selected publicly traded banks headquartered in Indiana, Kentucky, Ohio, Pennsylvania and West Virginia with assets between $3 and $18 billion. To perform this analysis, MHH used financial information as of and for the three months ended June 30, 2014, if available. Market price information was as of October 27, 2014. Certain financial data prepared by MHH, and as referenced in the tables presented below may not correspond to the data presented in ESB’s and WesBanco’s historical financial statements, as a result of the different periods, assumptions and methods used by MHH to compute the financial data presented.

Transaction multiples for the merger were evaluated two ways based on the exchange ratio of 0.502 and $1.76 cash consideration per share: 1) using the 15 day average closing price of WesBanco’s common stock as of October 27, 2014 to arrive at an implied value of the merger consideration of $17.65 per common share for ESB and 2) using the October 27, 2014 closing price (two days prior to announcement) of WesBanco’s common stock to arrive at an implied value of the merger consideration of $18.47 per common share for ESB. For each transaction referred to above, MHH derived and compared, among other things, the implied ratio of price per common share paid for the acquired company to:

• the latest closing price one day prior to the announcement of the acquisition ( “Premium to Market Value”);

• tangible book value per share of the acquired company based on the latest publicly available financial statements of the company available prior to the announcement of the acquisition;

• last-twelve-months earnings per share of the acquired company based on the latest publicly available financial statements of the company available prior to the announcement of the acquisition;

• assets of the acquired company based on the latest publicly available financial statements of the company available prior to the announcement of the acquisition; and

• deal premium, as measured against tangible book value, as a percent of core deposits.

The results of the analysis are set forth in the following table:

Transaction Price to:	WesBanco/ ESB Merger (15 day value)			WesBanco/ ESB Merger (1 day value):			Nationwide transactions since 1/1/12, deal value between $250mm & $350mm median:			Nationwide transactions since 1/1/12, assets between $1B & $5B median:			PA, MD, OH & WV transactions since 1/1/12, assets greater than $100mm median:			“Performance based” transactions since 1/1/12 median:

No company or transaction used as a comparison in the above analysis is identical to ESB, WesBanco or the merger. Accordingly, an analysis of these results is not mathematical. Instead, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies.

Financial Impact Analysis. MHH performed pro forma merger analysis on the combined projected income statement and balance sheet information of ESB and WesBanco. Assumptions regarding the accounting treatment, acquisition adjustments and cost savings were used to calculate the financial impact the merger would have on certain projected financial results of WesBanco. In the course of this analysis, MHH used earnings estimates for WesBanco for 2014 and 2015 from a nationally recognized earnings estimate consolidator and used earnings estimates for ESB for 2014, 2015 and 2016 from ESB’s management. This analysis indicated that the merger is expected to be accretive to WesBanco’s estimated earnings per share in 2015 and 2016. The analysis also indicated that the merger is expected to be dilutive to tangible book value per share for WesBanco and that WesBanco is expected to maintain well capitalized capital ratios. For all of the above analyses, the actual results achieved by WesBanco following the merger may vary from the projected results, and the variations may be material.

Discounted Dividends Analysis. MHH performed a discounted dividends analysis to estimate a range of the present values of after-tax cash flows that ESB could theoretically produce for dividends to equity holders through 2019 on a standalone basis. In performing this analysis, MHH used management’s earnings estimates for ESB for 2015 and 2016 and applied an earnings growth rate of 5.0% thereafter, and assumed discount rates ranging from 10.0% to 16.0%. The range of values was determined by adding the present value of projected cash flows to ESB shareholders from March 31, 2015 through 2019 and the present value of the terminal value of ESB’s common stock. In determining the cash flows available to shareholders, MHH assumed that ESB would maintain a tangible common equity to tangible asset ratio of 6.5% and would retain sufficient earnings to maintain that level. Any earnings in excess of what would need to be retained represented dividendable cash flows for ESB. In calculating the terminal value of ESB, MHH applied multiples ranging from 10.0 to 16.0 times 2019 projected earnings. This resulted in a range of values for ESB from $10.96 to $17.78 per share. In addition, MHH applied premiums ranging from 130% to 190% of 2019 projected tangible book value. This resulted in a range of values for ESB from $9.98 to $14.87 per share. The discounted dividends present value analysis is a widely used valuation methodology that relies on numerous assumptions, including growth rates, terminal values and discount rates. The analysis did not purport to be indicative of the actual values or expected values of ESB.

MHH, as part of its investment banking services, is regularly engaged in the independent valuation of businesses and securities in connection with mergers, acquisitions, private placements and valuations for corporate and other purposes. ESB and MHH have entered into an agreement whereby MHH has acted as financial advisor to ESB in connection with the merger. ESB has paid MHH a fee of $100,000 upon the execution of the engagement agreement and a fee of $550,000 upon the delivery of MHH’s fairness opinion.

- 70 -

Additionally, ESB has agreed to pay MHH a Contingent Fee at the time of closing equal to 1.25% of the aggregate transaction value against which both fees previously paid will be credited. In addition, ESB has agreed to reimburse MHH for reasonable out-of-pocket expenses and disbursements incurred in connection with its retention and to indemnify MHH for certain liabilities arising out of its engagement. During the two years preceding the date of its opinion to ESB, MHH has not received compensation (other than the $100,000 engagement retainer fee from ESB in connection with the merger) for investment banking services from ESB. MHH received a $25,000 engagement retainer fee from WesBanco in February 2014 for investment banking services unrelated to the merger.

Interests of Certain Persons in the Merger

In considering the recommendation of the ESB board of directors with respect to the merger agreement, ESB shareholders should be aware that certain persons, including the directors and executive officers of ESB, have interests in the merger that are in addition to their interests as shareholders of ESB generally. The ESB board of directors was aware of these interests as well as others and considered them in adopting the merger agreement and the transactions contemplated thereby. As described in more detail below, these interests include certain payments and benefits that may be provided to the executive officers upon completion of the merger, including cash severance and continued medical, life and disability insurance benefits. The dates and share prices used below to quantify these interests have been selected for illustrative purposes only. They do not necessarily reflect the dates on which certain events will occur and do not represent a projection about the future value of ESB common stock.

Cash Payment for Outstanding Options. Under the terms of the merger agreement, all ESB stock options that are outstanding and unexercised at the time of the merger, whether or not vested, will be cancelled, and in lieu thereof the holders of such options will be paid in cash an amount equal to the product of (i) the number of shares of ESB common stock subject to such option at the closing and (ii) an amount equal to the excess, if any, of $17.65 over the exercise price per share of such option, net of any cash which must be withheld under federal and state income and employment tax requirements. As of the date of this joint proxy statement/prospectus, the directors and executive officers of ESB and ESB Bank as a group held options to purchase an aggregate of [—] shares of ESB common stock, including options to purchase [—] shares which have not yet vested. If none of such options are exercised prior to completion of the merger, the directors and executive officers of ESB and ESB Bank as a group will receive an aggregate of $[—] million upon cancellation of their stock options. See “—Summary of Golden Parachute Arrangements” for the amounts payable to the named executive officers.

Acceleration of Vesting of Restricted Stock Awards. Under the terms of the merger agreement, each outstanding share of ESB restricted stock will vest in full at or prior to the effective time of the merger and will be entitled to receive the merger consideration. As of the date of this joint proxy statement/prospectus, the executive officers of ESB and ESB Bank held an aggregate of [—] shares of ESB restricted stock. See “— Summary of Golden Parachute Arrangements” for the amounts payable to the executive officers.

Employment Agreements with ESB and ESB Bank. ESB Bank maintains a three-year employment agreement with Ms. Zuschlag as President and Chief Executive Officer, with a current base salary of $592,600. On an annual basis, the board of directors of ESB Bank considers whether to renew the employment agreement for an additional year ending December 1 so the remaining term will be three years. The employment agreement is terminable with or without cause by ESB Bank. The employment agreement provides that in the event of an involuntary termination of employment without cause (including a termination by Ms. Zuschlag for “good reason,” which includes a material change in her position, salary or duties without her consent), Ms. Zuschlag would be entitled to (1) an amount of cash severance which is equal to three times her average annual compensation, as defined, over the most recent three years preceding the year in which the date of termination occurs, (2) continued participation in certain insurance plans of ESB Bank, including medical, dental, life and disability insurance plans, at no cost to her until the earlier of 36 months or the date she receives substantially

- 71 -

similar benefits from full-time employment by another employer, (3) if Ms. Zuschlag is still receiving medical and dental coverage after the end of the 36 month period referred to in clause (2), then she would be entitled to continued medical and dental coverage until the earlier of Ms. Zuschlag’s death or the date Ms. Zuschlag receives medical and dental coverage from a subsequent employer substantially similar to the coverage provided by ESB Bank, provided however, Ms. Zuschlag shall pay the employee share of the costs of such coverage provided pursuant to this clause (3) to the same extent as if she were still an employee, and (4) a lump sum cash payment equal to the projected cost of providing Ms. Zuschlag with benefits for a period of three years pursuant to any other employee benefit plans, programs or arrangements in which she was entitled to participate, excluding retirement plans, stock compensation plans and cash compensation plans. In the event Ms. Zuschlag’s continued participation in any group insurance plan is barred or would trigger the payment of an excise tax under Section 4980D of the Code, or if any such group insurance plan is discontinued, then ESB Bank shall either (1) provide substantially similar benefits under an alternative plan or (2) pay a lump sum cash amount to Ms. Zuschlag equal to the projected cost of providing continued coverage to Ms. Zuschlag until her projected date of death in the case of medical and dental coverage and until the three-year anniversary of her date of termination in the case of all other insurance plans. The employment agreement with ESB Bank provides that in the event any of the payments to be made thereunder or otherwise upon termination of employment are deemed to constitute “parachute payments” within the meaning of Section 280G of the Code, then such payments and benefits received thereunder shall be reduced by the minimum amount necessary to result in no portion of the payments and benefits being non-deductible by ESB Bank for federal income tax purposes. Parachute payments generally are payments in excess of three times the base amount, which is defined to mean the recipient’s average annual compensation from the employer includable in the recipient’s gross income during the most recent five taxable years ending before the date on which a change in control of the employer occurred. Recipients of parachute payments are subject to a 20% excise tax on the amount by which such payments exceed the base amount, in addition to regular income taxes, and payments in excess of the base amount are not deductible by the employer as compensation expense for federal income tax purposes.

ESB also has an employment agreement with Ms. Zuschlag to serve on terms substantially similar to the agreement entered into with ESB Bank, except as provided below. Ms. Zuschlag’s compensation, benefits and expenses are paid by ESB and ESB Bank in the same proportion as the time and services actually expended by her on behalf of each company. However, the agreement with ESB provides that severance payments payable to Ms. Zuschlag by ESB shall (1) include the amount by which the severance benefits payable by ESB Bank are reduced by her employment agreement with ESB Bank to avoid having ESB Bank make parachute payments under Section 280G of the Code, and (2) not be subject to reduction in the event of a change in control as are the amounts payable by ESB Bank. As a result, the severance benefits payable by ESB may constitute “parachute payments” under Section 280G of the Code. In addition, the agreement with ESB provides that ESB shall reimburse Ms. Zuschlag for any resulting excise taxes payable by her, plus such additional amount as may be necessary to compensate her for the payment of federal, state and local income, excise and other employment-related taxes on the additional payments.

Change in Control Agreement with ESB and ESB Bank. ESB and ESB Bank maintain change in control agreements with its Group Senior Vice Presidents, Messrs. Evanoski, Martz and Palkovich, and certain of its Senior Vice Presidents, including Mr. Canonge. The change in control agreements are intended to assist ESB and ESB Bank in maintaining a stable and competent management base. The agreements with the Group Senior Vice Presidents Evanoski, Martz and Palkovich provide for an initial three year term, and subject to satisfactory performance reviews, among other things, the term shall be extended on each anniversary of December 1 for an additional year so that the remaining term will be three years as of the annual renewal date, unless either the boards of directors of the employers or the executive provides contrary written notice to the other not less than 30 days in advance of such anniversary date. The agreements are automatically extended for an additional one year upon a change in control, as defined. The agreements provide that in the event of an involuntary termination of employment without cause following a change in control (including a termination by the executive for “good reason,” which includes a material change in the executive’s position, salary or duties without his consent), the executive would be entitled to (1) an amount of cash severance which is equal to three times his average annual

- 72 -

compensation, as defined, over the most recent three years preceding the year in which the date of termination occurs, (2) continued participation in certain insurance plans of the employers, including medical, dental, life and disability insurance plans, at no cost to the executive until the earlier of 36 months or the date the executive receives substantially similar benefits from full-time employment by another employer, (3) if the executive is still receiving medical and dental coverage after the end of the 36 month period referred to in clause (2), then he would be entitled to continued medical and dental coverage until the earlier of his death, the date on which he becomes eligible to receive benefits under Medicare or the date he receives medical and dental coverage from a subsequent employer substantially similar to the coverage provided by ESB Bank, provided however, the executive shall pay the employee share of the costs of such coverage provided pursuant to this clause (3) to the same extent as if he were still an employee, and (4) a lump sum cash payment equal to the projected cost of providing the executive with benefits for a period of three years pursuant to any other employee benefit plans, programs or arrangements in which he was entitled to participate, excluding retirement plans, stock compensation plans and cash compensation plans. In the event the executive’s continued participation in any group insurance plan is barred or would trigger the payment of an excise tax under Section 4980D of the Code, or if any such group insurance plan is discontinued, then ESB Bank shall either (1) provide substantially similar benefits under an alternative plan or (2) pay a lump sum cash amount to the executive equal to the projected cost of providing continued coverage to the executive until his projected date of eligibility to receive benefits under Medicare in the case of medical and dental coverage and until the three-year anniversary of his date of termination in the case of all other insurance plans. The agreements provide that if any of the payments or benefits to be provided thereunder or otherwise upon termination of employment are deemed to constitute a “parachute payment” within the meaning of Section 280G of the Code, which would cause the executive to incur an excise tax under Section 4999 of the Code, then ESB shall reimburse the executive for any resulting excise taxes payable by him, plus such additional amount as may be necessary to compensate the executive for the payment of federal, state and local income, excise and other employment-related taxes on the additional payments.

The change in control agreements entered into with certain of ESB’s and ESB Bank’s Senior Vice Presidents, including Mr. Canonge, are similar to the change in control agreements for the Group Senior Vice Presidents discussed above, except that the agreements with the Senior Vice Presidents provide for severance payments in the event that termination of employment or certain adverse actions are taken with respect to the executive’s employment within 24 months subsequent to a change in control in an amount equal to two times the respective executive’s annual compensation, as defined, and provide for continued benefits for only 24 months. In addition, the agreements provide that if any of the payments or benefits to be provided thereunder or otherwise upon termination of employment are deemed to constitute a “parachute payment” within the meaning of Section 280G of the Code, then the payments and benefits shall be reduced by the minimum amount necessary so that no excise taxes are triggered under Section 4999 of the Code.

Separation and Release and Waiver of Claims Agreements. In accordance with the merger agreement and in connection with the merger, WesBanco, WesBanco Bank, ESB and ESB Bank entered into separate separation and release and waiver of claims agreements (the “separation agreements”) with Charlotte A. Zuschlag, President and Chief Executive Officer of ESB and ESB Bank, and the following ESB Group Senior Vice Presidents: Charles P. Evanoski, Frank D. Martz and Todd F. Palkovich. The separation agreements provide for the executive’s separation from service with ESB and ESB Bank upon completion of the merger. The separation agreements specify the amount of cash severance to be paid to the executive upon completion of the merger, provide for special, one-time cash bonuses to each of the Group Senior Vice Presidents to be paid before the end of 2014, and retain each executive’s right to a Section 280G gross-up payment in the event such payment is subsequently deemed triggered. The separation agreements also provide for the release of claims against ESB, WesBanco and their subsidiaries, affiliates, directors, officers, employees and others. In the event the merger is terminated for any reason, the separation agreements will become null and void. When the amounts specified in the separation agreements are paid and the new employment agreements summarized below become effective, the current employment and change in control agreements of such executive officers will automatically terminate. See “— Summary of Golden Parachute Arrangements” beginning on page [—] for the amounts payable to the executive officers pursuant to their separation agreements.

New Employment, Non-Competition and Consulting Agreements. In accordance with the merger agreement and in connection with the merger, WesBanco Bank and WesBanco have entered into separate employment and non-competition agreements with Charlotte A. Zuschlag and each of the ESB Group Senior Vice Presidents: Charles P. Evanoski, Frank D. Martz and Todd F. Palkovich and a consulting agreement with Mr. Evanoski. The employment agreements for the ESB Group Senior Vice Presidents each run for a term beginning on the closing of the merger and ending on the last day of the month following the conversion of the ESB data system and provide for each to receive a salary equivalent to no less than each individual was receiving from ESB Bank on October 29, 2014, as well as customary WesBanco welfare benefits. The non-competition agreements require the individuals to refrain from competing with WesBanco and not to solicit employees and customers commencing on the effective date of the merger and extending for a period of one year for Mr. Evanoski and three years for Messrs. Martz and Palkovich. As compensation for these non-competition obligations, on the effective date of the merger Mr. Evanoski will receive $175,000, Mr. Martz will receive $480,000 and Mr. Palkovich will receive $550,000. Mr. Evanoski also entered into a Consulting Agreement with WesBanco generally covering transition, tax preparation and joint venture matters. The term of Mr. Evanoski’s Consulting Agreement is for two years commencing on the expiration of the employment agreement he entered into described above and provides for the payment to Mr. Evanoski of $2,916.67 per month during the term.

Ms. Zuschlag also entered into an employment agreement and a non-competition agreement with WesBanco and WesBanco Bank. Under the employment agreement, on the effective date of the merger Ms. Zuschlag will become a Development Officer for the Pittsburgh market for WesBanco Bank. The employment agreement term will run until Ms. Zuschlag reaches age 70. The employment agreement provides that Ms. Zuschlag is entitled to receive an annual base salary of $25,000 and certain other death, disability and welfare benefits. The non-competition agreement generally requires Ms Zuschlag to refrain from competing with WesBanco and not to solicit employees and customers commencing on the effective date of the merger and extending for a period of four years. As compensation for Ms. Zuschlag’s non-competition obligations, she will receive $1,061,000 on the effective date of the merger.

SERP Amendment. In connection with the merger, the ESB board of directors entered into Amendment No. 1 to ESB’s Amended and Restated Supplemental Executive Retirement Plan (the “SERP amendment”). The SERP amendment provides that the change in control SERP benefits payable following completion of the merger will not commence substantially sooner than they would as a result of a separation from service at the time of closing, and provides that the special, one-time bonuses to be paid to the Group Senior Vice Presidents in 2014 will not increase the amount of their SERP benefits.

Excess Benefit Plan Amendment. In connection with the merger, the ESB board of directors entered into Amendment No. 1 to ESB’s Amended and Restated Excess Benefit Plan (the “Excess Benefit Plan amendment”). The Excess Benefit Plan amendment provides that the special, one-time bonuses to be paid to the Group Senior Vice Presidents in 2014 will not increase the amount of their benefits under the Excess Benefit Plan.

Summary of Golden Parachute Arrangements

The following table sets forth the aggregate dollar value of the various elements of compensation that each named executive officer of ESB will receive that is based on or otherwise relates to the merger, assuming the following:

• the merger closes on February 6, 2015, which is the earliest date that we expect the merger to close (the actual closing date is more likely to be later in the first quarter of 2015 or early in the second quarter of 2015);

• the full-time employment of Ms. Zuschlag and Messrs. Evanoski, Martz, Palkovich and Canonge is terminated without cause immediately following the closing of the merger on February 6, 2015;

- 74 -

• Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich receive the lump sum payments set forth in the separation agreements and non-competition agreements summarized above, and Mr. Canonge receives the lump sum cash severance to which he is entitled under his current change in control agreement with ESB and ESB Bank;

• Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich receive payments and insurance benefits pursuant to their new part-time employment agreements (and, in the case of Mr. Evanoski, his part-time consulting agreement) with WesBanco, which agreements will become effective upon completion of the merger;

• the projected costs of providing continued health, dental, life, disability and accident insurance coverage is based on current premiums, which are assumed to increase by 10% on January 1^st of each year;

• the value of the unvested restricted stock awards that will have accelerated vesting upon completion of the merger equals the average per share closing price of WesBanco common stock for the five trading days following the first public announcement of the merger, which average price was $34.354 per share. Based on the exchange ratio of 0.502 shares of WesBanco common stock for each share of ESB common stock and the cash merger consideration of $1.76 for each share of ESB common stock, the merger consideration was assumed to aggregate $19.006 per share of ESB common stock; and

• the IRS discount rates for the month in which the merger is completed are equal to the IRS discount rates in effect for November 2014 — these rates change monthly and are used to compute present value amounts for insurance benefits and for parachute amounts associated with the accelerated vesting of unvested equity awards under Section 280G of the Code.

Any changes in these assumptions or estimates would affect the amounts shown in the following table. The actual value of the merger consideration upon completion of the merger may be higher or lower than the $19.006 per share of ESB common stock assumed above. Because the executive officers are not entitled to any pension or nonqualified deferred compensation benefit enhancements and are not expected to receive any tax reimbursements, the columns with respect to such benefits have been omitted from the following table.

(1) For Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich, represents the amounts payable to them pursuant to the separation agreements entered into concurrently with the execution of the merger agreement. These amounts represent a portion of the cash severance that such executives would have been entitled to under their respective employment or change in control agreements with ESB and ESB Bank, with such amounts designed to keep the total parachute payments to such executives below their respective Section 280G threshold in order to avoid excise taxes and tax gross-up payments. Such amounts include special, one-time bonuses to be paid in December 2014 for tax planning purposes as follows: Ms. Zuschlag, $0; Mr. Evanoski, $630,000; Mr. Martz, $100,000; and Mr. Palkovich, $100,000. The remaining portion of the payments to these four executives in the Cash column in the above table will be paid in a lump sum on the effective date of the merger. The remaining cash severance that these four executives would have been entitled to under their respective employment or change in control agreements with ESB and ESB Bank was allocated to the new non-competition, employment and/or consulting agreements that such executives entered into with WesBanco, with such amounts set forth in Note (4) below. The amount for Mr. Canonge represents the cash severance he is entitled to under his change in control agreement with ESB and ESB

- 75 -

Bank based on the sum of (a) two times his highest salary and bonus for the three years ending December 31, 2014, and (b) the projected cost of providing club dues and cell phone for 24 months, with such cash severance to be paid in a lump sum on the effective date of the merger. While the employment and change in control agreements that the five executives have with ESB and ESB Bank provide that the lump sum cash severance under such agreements would be paid upon a termination of employment concurrently with or following completion of the merger (i.e., a double-trigger arrangement), the payments pursuant to the separation agreements with Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich may be deemed to be a single-trigger arrangement since the executives will be re-hired by WesBanco on a part-time basis following completion of the merger.

(2) Represents the value of the unvested stock options and unvested restricted stock awards held by Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich and the value of the unvested stock options held by Mr. Canonge. The value of the unvested restricted stock awards (including accumulated cash dividends) is estimated to be $934,800 for Ms. Zuschlag and $287,625 for each of Messrs. Evanoski, Martz and Palkovich, based on the assumed merger consideration of $19.006 per share of ESB common stock. The value of the unvested stock options is $89,774 for Ms. Zuschlag, $43,098 for each of Messrs. Evanoski, Martz and Palkovich, and $17,451 for Mr. Canonge, based on the merger agreement which provides that stock options which remain unexercised immediately prior to the completion of the merger will be cashed out based upon the positive difference between $17.65 per share and the exercise price per share of the unexercised stock options. All of the unvested stock options and unvested restricted stock awards will become fully vested upon completion of the merger even if the executive’s employment is not terminated. This accelerated vesting is considered to be a single-trigger arrangement. Excludes the value of vested, in-the-money stock options, which will be cashed out upon completion of the merger in the event such options remain unexercised based upon the positive difference between $17.65 per share and the exercise price per share of the unexercised stock options. Assuming the vested stock options remain unexercised, the cash payments to be made upon cancellation of the vested stock options equal $1,173,563 for Ms. Zuschlag, $686,090 for Mr. Evanoski, $642,487 for Mr. Martz, $686,090 for Mr. Palkovich, and $80,189 for Mr. Canonge. Because we expect that these vested stock options will be exercised prior to completion of the merger based on the assumed merger consideration of $19.006 per share of ESB common stock, the value of these vested stock options has not been included in the above table.

(3) Represents the sum of (a) the projected cost of providing the executives with continued participation in all group insurance, life insurance, health and dental insurance, and disability and accident insurance for a period of three years for each of Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich and a period of two years for Mr. Canonge, in each case at no cost to the executives, and (b) the projected cost of providing continued health and dental insurance to Ms. Zuschlag for life and to each of Messrs. Evanoski, Martz and Palkovich until they become eligible for Medicare at age 65, with the executives paying the employee portion of the premiums for such continued coverage as if they were still an employee. If an executive obtains full-time employment with another employer during such period (prior to age 70 for Ms. Zuschlag) and is entitled to receive substantially similar benefits from the subsequent employer, or if the executive dies during such period, then the continued coverage will cease. The projected costs assume the insurance premiums increase by 10% each year, and the amounts have been discounted to present value based on IRS discount rates in effect for November 2014. In addition, WesBanco has agreed to pay the premiums of a Medicare supplement medical insurance plan once Ms. Zuschlag reaches age 70 for the remainder of her life, and we have assumed that the costs of such plan equal the costs of the employer premiums that would otherwise be paid under the group insurance plans. Of the total present value projected cost of $306,467 shown for Ms. Zuschlag, approximately $57,487 represents the present value of the aggregate projected cost of providing insurance coverage to her under her new employment agreement with WesBanco until age 70. While the employment and change in control agreements that the five executives have with ESB and ESB Bank provide for a continuation of the insurance benefits in the event of a termination of employment concurrently with or following completion of the merger (i.e., a double-trigger arrangement), the continuation of the insurance benefits for Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich may be deemed to be a single-trigger arrangement since such executives will be re-hired by WesBanco on a part-time basis following completion of the merger.

- 76 -

(4) Represents the sum of (a) the lump sum payments to be made upon completion of the merger to Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich pursuant to their non-competition agreements with WesBanco, (b) the aggregate salary of $150,000 to be paid in equal installments over six years to Ms. Zuschlag pursuant to her new part-time employment agreement with Wesbanco, and (c) the aggregate consulting fees of $70,000 to be paid in equal installments over two years to Mr. Evanoski pursuant to his new part-time consulting agreement with WesBanco. All of these agreements will become effective only upon completion of the merger. The non-competition agreements have a term of four years for Ms. Zuschlag, three years for each of Messrs. Martz and Palkovich, and one year for Mr. Evanoski. The lump sum payments to be made pursuant to the non-competition agreements are $1,061,000 for Ms. Zuschlag, $175,000 for Mr. Evanoski, $480,000 for Mr. Martz and $550,000 for Mr. Palkovich. The value of each of the non-competition agreements was determined by an independent third party. The payments pursuant to these agreements may be deemed to be a single-trigger arrangement.

(5) All of the amounts in this column with respect to Ms. Zuschlag and Messrs. Evanoski, Martz and Palkovich may be deemed to be attributable to a single-trigger arrangement, while $376,029 of the amount for Mr. Canonge is attributable to a double-trigger arrangement and only the $17,451 amount in the Equity column for Mr. Canonge is attributable to a single-trigger arrangement. The amounts in this column exclude the value of outstanding vested stock options held by the executives as shown in Note (2) above, as well as other vested benefits under ESB’s ESOP, 401(k) Plan, Supplemental Executive Retirement Plan and Excess Benefit Plan. Also excludes the salaries to be paid to Messrs. Evanoski, Martz and Palkovich under their short-term, part-time employment agreements with WesBanco, with such salaries to be paid at the current rate of salary for each of such executives. If the payments and benefits to Ms. Zuschlag or Messrs. Evanoski, Martz or Palkovich pursuant to their new separation, non-competition, employment and/or consulting agreements would constitute a parachute payment under Section 280G of the Internal Revenue Code, then each of the separation agreements preserve the right of such executives under their current employment or change in control agreements with ESB and ESB Bank to be reimbursed for any resulting excise taxes payable by such executive, plus such additional amount as may be necessary to compensate such executive for the payment of federal, state and local income, excise and other employment-related taxes on the additional payments. We have assumed that the payments to be made pursuant to the new employment agreements with WesBanco and Mr. Evanoski’s new consulting agreement with WesBanco represent reasonable compensation for the services to be actually rendered and that the payments pursuant to the new non-competition agreements represent reasonable value for the obligations of the executives under such agreements, with the effect being that none of the cash payments pursuant to such agreements are deemed to be parachute payments under Section 280G of the Internal Revenue Code. Mr. Canonge’s change in control agreement with ESB and ESB Bank provides that the payments and benefits shown in the above table will be reduced by the minimum amount necessary to avoid having a parachute payment under Section 280G of the Internal Revenue Code. Based upon the assumptions made, no excise tax reimbursements or gross-up payments to Ms. Zuschlag or Messrs. Evanoski, Martz or Palkovich will be required, and no reduction in the payments and benefits to Mr. Canonge will be required.

Employee Severance Benefits. Pursuant to the merger agreement, ESB employees who are not offered the opportunity to continue as employees of WesBanco or WesBanco Bank after the merger or who are terminated without cause within one year after the effective time of the merger, in the case of clauses (1), (3) and (4) below, or who are terminated without cause within ninety (90) calendar days after the effective time of the merger in the case of clause (2) below, will be entitled to receive:

(1) severance payments based on the number of years worked and the employee’s weekly rate of pay, subject to certain minimum and maximum amounts;

(2) certain outplacement consultation services at a cost not to exceed $2,000 per employee;

(3) accrued benefits, including vacation pay, through the date of termination of employment; and/or

- 77 -

(4) any rights to continuation of medical coverage to the extent such rights are required under applicable federal or state law and subject to the employee’s compliance with all applicable requirements for such continuation coverage, including payment of all premiums or other expenses related to such coverage.

Board of Directors Appointments. Pursuant to the merger agreement, Charlotte A. Zuschlag, ESB’s President and Chief Executive Officer, and Ronald W. Owen, a current member of the board of directors of ESB Bank, will be appointed to the board of directors of WesBanco at the effective time of the merger. Both director appointees will serve until the next meeting of WesBanco’s shareholders and will be nominated for election to the WesBanco board at that shareholder meeting and subsequent shareholder meetings until each has served a three-year term.

Indemnification. WesBanco has agreed that it will, following the effective time of the merger, indemnify, defend and hold harmless the current and former directors and officers of ESB against all costs, expenses, claims, damages or liabilities arising out of actions or omissions occurring at or prior to the effective time of the merger to the fullest extent permitted by applicable law, including provisions relating to advances of expenses. The merger agreement further provides that WesBanco will obtain six years of extended liability insurance to provide for continued coverage of ESB’s directors and officers with respect to matters occurring prior to the effective time of the merger, subject to a cap that limits the amount that WesBanco must expend for such liability insurance to no more than an aggregate of $250,000.

Ownership by ESB Officers and Directors. As of the ESB record date, the directors and executive officers of ESB beneficially owned, in the aggregate, [—] shares of ESB common stock, representing approximately [—]% of the outstanding shares of ESB common stock. Directors and executive officers of ESB will be treated the same as other ESB shareholders with respect to their ownership of outstanding ESB common stock.

Regulatory Approvals

Completion of the merger and the bank merger are each subject to certain federal and state bank regulatory agency filings and approvals. WesBanco and ESB cannot complete the merger and the bank merger unless and until WesBanco and ESB receive all necessary prior approvals from the applicable bank regulatory authorities. WesBanco and ESB have agreed to use their best efforts to obtain all such necessary prior approvals required to consummate the transactions contemplated by the merger agreement. Neither WesBanco nor ESB can predict whether or when WesBanco and ESB will obtain the required regulatory approvals, waivers or exemptions necessary for the merger of WesBanco with ESB and the merger of WesBanco Bank with ESB Bank.

Federal Deposit Insurance Corporation. The bank merger is subject to the approval by the Federal Deposit Insurance Corporation (“FDIC”) under the Bank Merger Act. In granting its approval under the Bank Merger Act, the FDIC must consider, among other factors, the competitive effect of the merger, the managerial and financial resources and future prospects of the merging banks, the effect of the merger on the convenience and needs of the communities to be served, including the records of performance of the merging banks in meeting the credit needs of the communities under the Community Reinvestment Act, the effectiveness of the merging banks in combating money laundering activities, and the risk that would be posed by the merger to the stability of the United States banking or financial system. Applicable regulations require publication of notice of the application and an opportunity for the public to comment on the application in writing.

The bank merger (the completion of which is not a condition to the merger) may not be consummated until 30 days after the approval of the FDIC (or such shorter period as the FDIC may prescribe with the concurrence of the United States Department of Justice, but not less than 15 days), during which time the Department of Justice may challenge the bank merger on antitrust grounds.

Federal Reserve Board. The merger requires the approval of the Federal Reserve Board pursuant to the Bank Holding Company Act of 1956, as amended, unless the Federal Reserve Board is willing to grant a waiver

- 78 -

pursuant to its regulations allowing for such waivers. WesBanco intends to file a request for such waiver. If a waiver is not received, the Federal Reserve Board will also consider factors such as financial and managerial resources, future prospects, the convenience and needs of the community and competitive factors. In such case, the merger may not be consummated until 30 days after the approval of the Federal Reserve Board (or such shorter period as the Federal Reserve Board may prescribe with the concurrence of the United States Department of Justice, but not less than 15 days), during which time the Department of Justice may challenge the merger on antitrust grounds.

The commencement of an antitrust action by the Department of Justice would stay the effectiveness of the Federal Reserve Board or FDIC approval, as the case may be, unless a court specifically orders otherwise. In reviewing the merger and the bank merger, the Department of Justice could analyze the merger’s effect on competition differently than the Federal Reserve Board and the FDIC, and it is possible that the Department of Justice could reach a different conclusion than the applicable banking regulator regarding the merger’s (or the bank merger’s) competitive effects.

West Virginia Division of Financial Institutions. Both the merger and the bank merger require the approval of the West Virginia Division of Financial Institutions.

Pennsylvania Department of Banking. The merger also requires the approval of the Pennsylvania Department of Banking under the Pennsylvania Banking Code of 1965.

Other Requisite Approvals, Notices and Consents. The prior written approval of the Pennsylvania Department of Banking is not required for the bank merger because the resulting institution will be a West Virginia banking corporation. Pennsylvania law does require WesBanco to provide certain notice and documents to the Pennsylvania Department of Banking regarding the proposed bank merger.

Neither ESB nor WesBanco is aware of any other regulatory approvals required for completion of the merger other than approvals we describe above. Should WesBanco or ESB require any other approvals, ESB and WesBanco presently contemplate both of us would seek to obtain such approvals. There can be no assurance, however, that WesBanco and ESB can obtain any other approvals, if required.

There can be no assurance that the regulatory authorities described above will approve the merger or the bank merger, and if such mergers are approved, there can be no assurance as to the date on which WesBanco and ESB will receive such approvals. The mergers cannot proceed in the absence of the receipt of all requisite regulatory approvals.

The approval of any application merely implies the satisfaction of regulatory criteria for approval. Any such approval does not include review of the merger from the standpoint of the adequacy of the merger consideration our shareholders will receive upon the merger. Further, regulatory approvals do not constitute an endorsement or recommendation of the merger.

No Appraisal or Dissenters’ Rights

WesBanco shareholders. Under West Virginia law, holders of a corporation’s common stock are not entitled to exercise appraisal rights if the shares will remain outstanding after the merger. Consequently, because WesBanco is the surviving entity and its shares of common stock will remain outstanding after the effective time of the merger, WesBanco shareholders will not have the right to exercise appraisal or dissenters’ rights. If the merger is completed, WesBanco shareholders who voted against the issuance of shares of WesBanco common stock in connection with the merger will be treated the same as shareholders who voted for the issuance of shares of WesBanco common stock in connection with the merger. Therefore, if you own shares of WesBanco common stock on the WesBanco record date but you are against the merger, you may vote against the issuance of shares of WesBanco common stock in connection with the merger but you may not exercise appraisal or dissenters’ rights for your WesBanco shares.

- 79 -

ESB shareholders. Under Pennsylvania law, holders of a corporation’s common stock are not entitled to exercise dissenters’ rights if shares of the corporation are registered on a national securities exchange, designated as a national market system security on an interdealer quotation system by the Financial Industry Regulatory Authority or held beneficially or of record by more than 2,000 persons. Consequently, because ESB’s common stock is currently listed on Nasdaq Global Select Market, ESB shareholders will not have the right to exercise dissenters’ or appraisal rights. If the merger is completed, ESB shareholders who voted against the adoption of the merger agreement will be treated the same as ESB shareholders who voted for the adoption of the merger agreement and their ESB shares will automatically be converted into the right to receive the merger consideration. Therefore, if you own shares of ESB common stock on the ESB record date but you are against the merger, you may vote against adoption of the merger agreement but you may not exercise dissenters’ or appraisal rights for your ESB shares.

Delisting and Deregistration of ESB Common Stock Following the Merger

If the merger is completed, ESB common stock will be delisted from the Nasdaq Global Select Market and will be deregistered under the Securities Exchange Act of 1934, as amended.

Management Following the Merger

Each of the current directors and executive officers of WesBanco will continue to serve in those capacities following the merger. For information as to their identities, backgrounds, compensation and certain other matters relating to WesBanco’s directors and executive officers, please refer to WesBanco’s proxy statement for its 2014 annual meeting of shareholders, which is incorporated by reference herein. See ‘Where You Can Find More Information about WesBanco and ESB.” Charlotte A. Zuschlag, ESB’s President and Chief Executive Officer, will be appointed to the board of directors of WesBanco at the effective time of the merger. In addition, Ronald W. Owen, a member of the board of directors of ESB Bank, will be appointed to the board of directors of WesBanco at the effective time of the merger. For information as to the identities, backgrounds, compensation and certain other matters relating to ESB’s directors, including Ms. Zuschlag, please refer to ESB’s proxy statement for its 2014 annual meeting of shareholders, which is incorporated by reference herein. See ‘Where You Can Find More Information about WesBanco and ESB.” For more information about Mr. Owen, see below.

Ronald W. Owen. Director of ESB Bank since 2010. Age 65. Mr. Owen is employed as Vice President — Agency Marketing for Fidelity National Title, located in Pittsburgh, Pennsylvania. At Fidelity National Title, Mr. Owen has primary responsibility for major agent maintenance and development with realtors, attorneys, bankers and independent title companies in Pennsylvania, New Jersey and Ohio. Previously, Mr. Owen was a Senior Relationship Executive at First American Title, located in Pittsburgh, Pennsylvania from February 2009 until October 2014. Mr. Owen is a director of Gateway Rehabilitation Centers, headquartered in Pittsburgh, Pennsylvania, as well as a trustee of Thiel College, located in Greenville, Pennsylvania.

Mr. Owen received director fees of $27,080 from ESB Bank and its subsidiaries 2013. In addition, on November 19, 2013, Mr. Owen was granted stock options to purchase 4,800 shares of ESB common stock at an exercise price of $13.36, which options vested 20% immediately and 20% on each anniversary of the date of grant. (The aggregate grant date value of the options computed in accordance with FASB ASC Topic 718 was $18,504.)

Accounting Treatment

In accordance with Financial Accounting Standards Board, Accounting Standards Codification 805, Business Combinations, WesBanco will account for the merger as an “acquisition.” Under acquisition accounting, ESB’s assets, including identifiable intangible assets, and liabilities, including executory contracts and other commitments, as of the effective time of the merger will be recorded at their respective fair values and added to the balance sheet of WesBanco. Any excess of the purchase price over the fair values will be recorded as goodwill. Financial statements of WesBanco issued after the merger will include these fair values and ESB’s results of operations from the effective time of the merger.

Material U.S. Federal Income Tax Consequences of the Merger

The following discussion addresses the material United States federal income tax consequences of the merger to holders of ESB common stock. The discussion is based on the Code, Treasury regulations promulgated thereunder, administrative rulings and practice, and judicial decisions, all as currently in effect and all of which are subject to change (possibly with retroactive effect) and to differing interpretations. Any such change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion applies only to ESB shareholders that hold their ESB common stock as a capital asset within the meaning of Section 1221 of the Code. This discussion does not address all aspects of United States federal taxation that may be relevant to a particular shareholder in light of its personal circumstances or to shareholders subject to special treatment under the United States federal income tax laws, including:

• banks, financial institutions or trusts,

• tax-exempt organizations,

• insurance companies,

• dealers in securities or foreign currency,

• traders in securities who elect to apply a mark-to-market method of accounting,

• pass-through entities and investors in such entities,

• real estate investment trusts,

• regulated investment companies,

• foreign persons,

• shareholders who received their ESB common stock through the exercise of employee stock options, holders of options to acquire ESB common stock, or holders who acquired their ESB common stock through a tax-qualified retirement plan or otherwise as compensation, and

• shareholders who hold ESB common stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated investment.

In addition, the discussion does not address any alternative minimum tax or any state, local or foreign tax consequences of the merger.

Each holder of ESB common stock should consult its tax advisor with respect to the particular tax consequences of the merger to such holder.

In connection with the filing with the SEC of the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part, K&L Gates LLP, tax counsel to WesBanco, has rendered its tax opinion to WesBanco and Silver, Freedman, Taff & Tiernan LLP, tax counsel to ESB, has rendered its tax opinion to ESB addressing the U.S. federal income tax consequences of the merger as described below. In rendering their respective tax opinions, each counsel relied upon representations and covenants, including those contained in certificates of officers of WesBanco and ESB, reasonably satisfactory in form and substance to each such counsel. If any of the representations or assumptions upon which the opinions are based are inconsistent with the actual facts, the U.S. federal income tax consequences of the merger could be adversely affected. Copies of the tax opinions are attached as Exhibits 8.1 and 8.2 to the Registration Statement on Form S-4.

The merger is conditioned upon receipt at closing by ESB of a legal opinion from Silver, Freedman, Taff & Tiernan LLP and upon receipt at closing by WesBanco of a legal opinion from K&L Gates LLP in each case, dated the closing date of the merger and to the effect that the merger will be treated as a “reorganization” within the meaning of Section 368(a) of the Code. Neither of these opinions will be binding on the Internal Revenue Service or the courts, and neither ESB nor WesBanco intends to request a ruling from the Internal Revenue

- 81 -

Service regarding the United States federal income tax consequences of the merger. Consequently, no assurance can be given that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of those set forth below.

The opinions of K&L Gates LLP and Silver, Freedman, Taff & Tiernan LLP to be issued at closing will rely on certain assumptions that customarily are made with respect to transactions of this kind. The opinions also will rely on certain factual representations contained in officers’ certificates of ESB and WesBanco. K&L Gates LLP and Silver, Freedman, Taff & Tiernan LLP will assume such representations to be true, correct and complete. If any such representation cannot be made on the effective date of the merger, or any such representation or assumption is incorrect, then K&L Gates LLP and Silver, Freedman, Taff & Tiernan LLP may be unable to render the opinions upon which the closing is conditioned.

The remainder of this discussion assumes that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code, in which case neither WesBanco nor ESB will recognize any gain or loss as a result of the merger.

Receipt of WesBanco Common Stock and Cash

Gain But No Loss. An ESB shareholder will recognize gain, but not loss, in an amount equal to the lesser of:

• the amount of gain realized with respect to the ESB common stock surrendered in the exchange; and

• the amount of cash received (other than cash received in lieu of a fractional share of WesBanco common stock, which will be taxed as discussed below under “— Cash Received in Lieu of a Fractional Share of WesBanco Common Stock”).

The amount of gain realized with respect to the ESB common stock exchanged will equal the excess, if any, of:

• the sum of the cash received plus the fair market value of WesBanco common stock received over

• the ESB shareholder’s adjusted tax basis in such ESB common stock.

For this purpose, gain or loss must be calculated separately for each identifiable block of shares of ESB common stock surrendered in the merger, and a loss realized on one block of shares may not be used to offset a gain realized on another block of shares. Holders should consult their tax advisors regarding the manner in which cash and shares of WesBanco common stock should be allocated among different blocks of their ESB common stock surrendered in the merger. In addition, for purposes of calculating gain or loss, the fair market value of WesBanco common stock is based on the trading price of that stock on the date of completion of the merger.

For purposes of determining the character of this gain, such ESB shareholder will be treated as having received only WesBanco common stock in exchange for such shareholder’s ESB common stock, and as having immediately redeemed a portion of such WesBanco common stock for the cash received. Unless this deemed redemption is treated as a dividend (as described below in “— Possible Treatment of Cash as a Dividend”) to the extent of such shareholder’s ratable share of accumulated earnings and profits of ESB, the gain will be capital gain if the ESB common stock is held by such shareholder as a capital asset at the time of the merger. Any capital gain will be long-term capital gain if, as of the date the merger is completed, the holding period for such ESB common stock is more than one year.

Tax Basis. The aggregate adjusted tax basis of WesBanco common stock received in the merger generally will be equal to the aggregate adjusted tax basis of the shares of ESB common stock surrendered in the merger, reduced by the amount of cash received by the holder in the merger (excluding any cash received in lieu of a fractional share), and increased by the amount of any gain recognized by the holder in the merger (including any

- 82 -

portion of the gain that is treated as a dividend, as described below under “— Possible Treatment of Cash as a Dividend,” but excluding any gain or loss resulting from the deemed issuance and redemption of fractional shares as described below under “— Cash Received in Lieu of a Fractional Share of WesBanco Common Stock”).

Holding Period. The holding period of WesBanco common stock received in the merger (including fractional shares of WesBanco common stock deemed received and redeemed as described below) will include the holding period of the ESB common stock exchanged therefor.

Taxation of Capital Gain. Except as described under “— Possible Treatment of Cash as a Dividend” below, gain that holders of ESB common stock recognize in connection with the merger generally will constitute capital gain and will constitute long-term capital gain if such holders have held (or are treated as having held) their ESB common stock for more than one year as of the effective date of the merger. Long-term capital gains recognized by non-corporate taxpayers are subject to reduced tax rates compared to ordinary income rates.

Possible Treatment of Cash as a Dividend. In general, the determination of whether gain recognized by an ESB shareholder who exchanges its shares of ESB common stock for a combination of WesBanco common stock and cash will be treated as capital gain or as a dividend distribution will depend on whether, and to what extent, the merger reduces the holder’s deemed percentage ownership in WesBanco. For purposes of this determination, each holder of ESB common stock is treated as if it first exchanged all of its shares of ESB common stock solely for WesBanco common stock and then WesBanco immediately redeemed a portion of the WesBanco common stock in exchange for the cash the holder actually received. The gain recognized in this deemed redemption will be treated as capital gain and not as a dividend equivalent if the deemed redemption is (1) “substantially disproportionate” with respect to the holder, or (2) “not essentially equivalent to a dividend” (i.e., the deemed redemption results in a “meaningful reduction” in the ESB shareholder’s interest in WesBanco common stock). The exchange will be substantially disproportionate with respect to the holder if the holder’s percentage interest in WesBanco common stock (including stock constructively owned by the holder) immediately after the merger is less than 80% of what the percentage interest would have been if, hypothetically, the holder had received solely WesBanco common stock in exchange for all ESB common stock owned or constructively owned by the holder before the merger. Whether an exchange would result in a meaningful reduction depends on the particular ESB shareholder’s facts and circumstances. The Internal Revenue Service has ruled that a shareholder in a publicly-held corporation whose stock interest is minimal (e.g., less than 1%) and who exercises no control with respect to corporate affairs can be considered to have a “meaningful reduction” if that shareholder has a minor reduction in its percentage stock ownership in the deemed redemption. Accordingly, the gain recognized in the deemed exchange by such a shareholder would be treated as capital gain. In determining an ESB shareholder’s interest in WesBanco common stock, the ESB shareholder may be deemed to own any shares of WesBanco common stock owned, or constructively owned, by certain persons related to such ESB shareholder or that are subject to an option held by the ESB shareholder or a related person.

These rules are complex and dependent upon the specific factual circumstances particular to each ESB shareholder. Consequently, each holder should consult its tax advisor as to the application of these rules to the particular facts relevant to such holder. ESB shareholders that are corporations should consult their tax advisors regarding their eligibility for a dividends received deduction and the treatment of the dividend as an “extraordinary dividend” under Section 1059 of the Code.

Cash Received in Lieu of a Fractional Share of WesBanco Common Stock

A holder of ESB common stock who receives cash instead of a fractional share of WesBanco common stock will generally be treated as having received such fractional share and then as having received such cash in redemption of that fractional share by WesBanco. Unless the receipt of such cash is treated as a dividend under the principles discussed above under “— Possible Treatment of Cash as a Dividend,” a holder of ESB common stock generally will recognize gain or loss equal to the difference between the amount of cash received and the ESB shareholder’s portion of such shareholder’s aggregate adjusted tax basis of the shares of ESB common stock

- 83 -

exchanged in the merger which is allocable to the fractional share. Such gain or loss will be long-term capital gain or loss if, as of the effective date of the merger, the holding period for such shares is more than one year. The deductibility of capital losses is subject to limitations.

Net Investment Income Tax

A holder that is an individual is subject to a 3.8% tax on the lesser of: (i) his or her “net investment income” for the relevant taxable year; or (ii) the excess of his or her modified adjusted gross income for the taxable year over a certain threshold (between $125,000 and $250,000 depending on the individual’s U.S. federal income tax filing status). Estates and trusts are subject to similar rules. Net investment income generally would include any capital gain recognized in connection with the merger (including any gain treated as a dividend), as well as, among other items, other interest, dividends, capital gains and rental or royalty income received by such individual. Holders should consult their tax advisors as to the application of this additional tax to their circumstances.

Backup Withholding and Information Reporting

Backup withholding at a 28% rate will generally apply to merger consideration that includes cash if the exchanging ESB shareholder fails to properly certify that it is not subject to backup withholding, generally on Internal Revenue Service Form W-9. Certain holders, including, among others, United States corporations, are not subject to backup withholding, but they may still need to furnish a Form W-9 or otherwise establish an exemption. Any amounts withheld from payments to an ESB shareholder under the backup withholding rules are not additional taxes and will be allowed as a refund or credit against the shareholder’s United States federal income tax liability, provided that the required information is timely furnished to the Internal Revenue Service.

A holder of ESB common stock who receives WesBanco common stock as a result of the merger will be required to retain records pertaining to the merger. Each holder of ESB common stock who is required to file a U.S. federal income tax return and who is a “significant holder” that receives WesBanco common stock in the merger will be required to file a statement with such U.S. federal income tax return in accordance with Treasury Regulations Section 1.368-3 setting forth such holder’s basis (determined immediately prior to the exchange) in the ESB common stock surrendered and the fair market value (determined immediately prior to the exchange) of the ESB common stock that is exchanged by such significant holder. A “significant holder” is a holder of ESB common stock who, immediately before the merger, owned at least 5% of the outstanding stock of ESB or securities of ESB with a basis for federal income taxes of at least $1.0 million.

The foregoing discussion is intended only as a summary and does not purport to be a complete analysis or listing of all potential United States federal income tax consequences of the merger. You are urged to consult your tax advisors concerning the United States federal, state, local and foreign tax consequences of the merger to you.

Conduct of Business Prior to the Merger

Pursuant to the merger agreement, WesBanco and ESB have agreed that, until the merger becomes effective or the merger agreement is terminated, whichever occurs first, each will, among other things and with some exceptions:

• except for the use of information in preparing this joint proxy statement/prospectus and in connection with other required governmental filings, hold all information relating to the transactions contemplated by the merger agreement in the strictest confidence and not use or disclose any of such information except after such information (A) otherwise is or becomes generally available to the public, (B) was already known to the party receiving the information on a nonconfidential basis prior to the disclosure or (C) is subsequently disclosed to the party receiving the information on a nonconfidential basis by a third party having no obligation of confidentiality to the party disclosing the Information;

• consult with the other party with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and governmental and regulatory authorities necessary or advisable to consummate the transactions contemplated by the merger agreement and each party will keep the other apprised of the status of material matters relating to completion of the transactions contemplated by the merger agreement;

• upon request, furnish the other party with all information concerning itself, its subsidiaries, directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with any filing, notice or application made by or on behalf of such other party or of its subsidiaries to any third party or governmental or regulatory authority;

• not (A) knowingly take any action that would, or would be reasonably likely to, prevent or impede the merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986; or (B) knowingly take any action that is intended or is reasonably likely to result in (i) any of its representations and warranties set forth in the merger agreement being or becoming untrue in any material respect, (ii) any of the conditions of the merger, as set forth in the merger agreement, not being satisfied, or (iii) a material violation of any provision of the merger agreement, except, in each case, as may be required by applicable law;

• promptly shall notify the other party in writing if the party becomes aware of any fact or condition that (A) causes or constitutes a breach in any material respect of any of such party’s representations and warranties or (B) would (except as expressly contemplated by the merger agreement) cause or constitute a breach in any material respect of any such representation or warranty had such representation or warranty been made as of the time of occurrence or discovery of such fact or condition. Should any such fact or condition require any change in the breaching party’s disclosure schedule, that party shall promptly deliver to the other party a supplement to its disclosure schedule specifying such change. During the same period, each party shall promptly notify the other party of (A) the occurrence of any breach in any material respect of any of the party’s or its subsidiaries’ covenants contained in the merger agreement, (B) the occurrence of any event that may make the satisfaction of the conditions in the merger agreement impossible or unlikely in any material respect or (C) the occurrence of any event that is reasonably likely, individually or taken with all other facts, events or circumstances known to the disclosing party, to result in a material adverse effect with respect to the disclosing party; and

• coordinate the payment of any dividends and the record date and payment dates relating thereto, such that ESB shareholders (who will become WesBanco shareholders after the merger) shall not receive two dividends, or fail to receive one dividend, from ESB and/or WesBanco for any single calendar quarter.

- 85 -

Conditions to the Merger

The respective obligations of WesBanco and ESB to effect the merger are subject to the following conditions, among others:

• the adoption of the merger agreement by the shareholders of ESB;

• the approval of the issuance of shares of WesBanco common stock in connection with the merger by the shareholders of WesBanco;

• the absence of any order to restrain, enjoin, or otherwise prevent the consummation of the merger entered by any court or administrative body which remains in effect on the date the merger closes;

• the effectiveness of the Registration Statement on the date the merger closes;

• the absence of a pending or threatened stop order or proceedings seeking a stop order suspending the effectiveness of the Registration Statement or any amendments thereto;

• the receipt of all material governmental or other consents, approvals, and permissions;

• that the merger will not violate any non-appealable final order, decree or judgment of any court or governmental body having competent jurisdiction;

• on or before the date the merger closes, the receipt of an opinion from each party’s tax counsel to the effect that for federal income tax purposes the merger will be treated as a tax-free reorganization within the meaning of Section 368(a) of the Code, and regarding certain other tax matters;

• the accuracy in all material respects of the representations and warranties of the parties and the performance by the parties in all material respects of all of their obligations set forth in the merger agreement, and the receipt of a certificate from an appropriate officer certifying the foregoing; and

• the shares of WesBanco common stock to be issued in the merger shall have been approved for listing on Nasdaq.

In addition to the conditions discussed above, WesBanco’s obligation to consummate the merger is conditioned upon the receipt of all consents and approvals required to be obtained by WesBanco.

Termination of the Merger Agreement

The merger agreement may be terminated at any time prior to the closing of the merger, either before or after the special meetings of the WesBanco or ESB shareholders:

• by mutual written consent of ESB and WesBanco;

• by either WesBanco or ESB if the other party shall have breached any of its representations or warranties in a manner that would have a material adverse effect or if the other party shall have materially failed to comply with any of its covenants or agreements under the merger agreement and which breach or non-compliance is not cured within thirty calendar days of notice thereof;

• by either WesBanco or ESB if the merger has not closed by July 31, 2015, and such failure to close is not caused by a breach of the merger agreement by the terminating party;

• by either WesBanco or ESB if the ESB shareholders do not adopt the merger agreement at the ESB special meeting, or any adjournment thereof;

• by either WesBanco or ESB if the WesBanco shareholders do not approve the issuance of shares of WesBanco common stock in connection with the merger at the WesBanco special meeting, or any adjournment thereof;

- 89 -

• by either WesBanco or ESB if the governmental approvals required to consummate the merger are denied by a final non-appealable action; or

WesBanco may terminate the merger agreement:

• if ESB’s board of directors (A) modifies, qualifies, withholds or withdraws its recommendation, to its shareholders, that they should approve and adopt the merger agreement, or makes any statement, filing or release, in connection with the special meeting of the ESB shareholders or otherwise which is inconsistent with the recommendation of ESB’s board of directors that ESB shareholders approve and adopt the merger agreement, (B) breaches its obligations to call, give notice of and commence the special meeting of ESB shareholders, (C) approves or recommends an Acquisition Proposal (as defined below on page [—]), (D) fails to publicly recommend against a publicly announced Acquisition Proposal within ten (10) business days of being requested to do so by WesBanco, (E) fails to publicly reconfirm its recommendation, to the ESB shareholders, that they adopt the merger agreement, within ten (10) business days of being requested to do so by WesBanco, or (F) resolves or otherwise determines to take, or announces an intention to take, any of the foregoing actions; or

• if there shall have been a material breach of ESB’s covenant not to solicit competing offers.

In addition, ESB may terminate the merger agreement:

• in order to enter into an agreement with respect to an unsolicited proposal that if consummated would be reasonably likely to result in a transaction more favorable to ESB’s shareholders from a financial point of view, provided that certain other terms and conditions contained in the merger agreement are also complied with, and ESB pays the termination fee described below; or

• if there is a substantial decline in WesBanco’s stock price that is not generally experienced by comparable banks, as described in detail below.

The operation of the conditions permitting ESB to terminate the merger agreement based on a decrease in the market price of the WesBanco common stock reflects the parties’ agreement that ESB shareholders will assume the risk of a decline in value of the WesBanco common stock to $$27.98 per share under any circumstances and that ESB shareholders will assume the risk of a more significant decline in value of WesBanco common stock unless the percentage decline from $32.92 to the average value of WesBanco common stock during the ten (10) consecutive trading day period ending on the Determination Date is more than 15% greater than the percentage decrease, if any, in the closing value of the Nasdaq Bank Index from October 29, 2014 to the Determination Date. The purpose of this agreement is that a decline in the value of WesBanco’s common stock which is comparable to the decline in the value of an index of comparable publicly-traded stocks is indicative of a broad-based change in market and economic conditions affecting the financial services industry generally rather than factors which affect the value of the WesBanco common stock in particular.

Specifically, ESB may terminate the merger agreement during the five-day period (“Election Period”) beginning on the date that is the first to occur of (A) the first date on which all required bank regulatory approvals have been received or (B) the date on which ESB’s shareholders adopt the merger agreement (such first occurring date being the “Determination Date”) if all of the following occur:

(i) the average daily closing price of a share of WesBanco common stock during the ten (10) consecutive trading days ending on the Determination Date (the “WesBanco Ending Price”) is less than $27.98;

(ii) the quotient obtained by dividing the WesBanco Ending Price by $32.92 (the “WesBanco Starting Price”) is less than the difference obtained by subtracting 0.15 from the quotient obtained by dividing the closing value of the Nasdaq Bank Index on the Determination Date by 2,578.49, which was the closing value of the Nasdaq Bank Index on October 29, 2014 (the “Index Ratio”);

(iii) ESB notifies WesBanco in writing of ESB’s intention to terminate the merger agreement during the Election Period; and

- 90 -

(iv) WesBanco elects not to increase the exchange ratio in accordance with the formula described below within the five-day period following its receipt of notice that ESB intends to so terminate the merger agreement.

Even if the first two conditions described above are met, the ESB board of directors may elect not to terminate the merger agreement. Any decision to terminate the merger agreement will be made by the ESB board of directors in light of all of the circumstances existing at the time. Prior to making any decision to terminate the merger agreement, the ESB board of directors would consult with its financial and other advisors and would consider all financial and other information it deemed relevant to its decision, including whether the then current consideration to be received in the merger would deliver more value to ESB shareholders than the value that could be expected in the event ESB were to continue as an independent company (which would occur if the ESB board of directors were to elect to abandon the merger and WesBanco determined not to increase the exchange ratio). In addition, the ESB board of directors would consider whether, in light of market and other industry conditions at the time of such decision, the exchange ratio continued to be fair from a financial point of view to ESB’s shareholders. If ESB elected not to terminate the merger agreement, which it could do without any action on the part of ESB shareholders, the exchange ratio of WesBanco common stock would remain 0.502.

If each of the first two conditions set forth above were satisfied and the ESB board of directors elected to terminate the merger agreement, WesBanco would have the option of increasing the consideration payable to ESB shareholders by adjusting the exchange ratio as described below. WesBanco is under no obligation to adjust the exchange ratio and there can be no assurance that WesBanco would elect to adjust the exchange ratio to prevent the termination of the merger agreement. Any decision would be made by WesBanco in light of the circumstances existing at the time. If WesBanco elected to adjust the exchange ratio, ESB could not terminate the merger agreement as a result of the above-described circumstances.

The operation and effect of the provisions of the merger agreement dealing with a decline in the market price of WesBanco’s common stock may be illustrated by the following three scenarios:

(1) One scenario is that the WesBanco Ending Price is above $27.98. In this event, ESB would not have the right to terminate the merger agreement pursuant to these provisions.

(2) A second scenario is that the WesBanco Ending Price is less than $27.98 but that the percentage decline in the price of the WesBanco common stock from the initial measurement price of $32.92 is not more than 15% greater than the percentage decline, if any, in the closing value of the Nasdaq Bank Index. Under this scenario, ESB would not have the right to terminate the merger agreement.

(3) A third scenario is that the WesBanco Ending Price is less than $27.98 and the percentage decline in the price of WesBanco common stock from the initial measurement price is more than 15% greater than the decline in the closing value of the Nasdaq Bank Index. Under this scenario, ESB would have the right, but not the obligation, to terminate the merger agreement unless WesBanco elected to increase the exchange ratio to equal the number obtained by dividing $15.89 by the greater of (A) $27.98 or (B) the product obtained by multiplying $27.98 by the Index Ratio.

If, between October 29, 2014 and the Determination Date, WesBanco declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction, the prices for the common stock of WesBanco shall be appropriately adjusted for purposes of the above-discussed termination provision.

In the event of any termination of the merger agreement by either ESB or WesBanco as provided above, all further obligations of ESB and WesBanco under the merger agreement, except with respect to specified matters, will terminate.

Expenses

Whether or not the merger is completed, all legal and accounting fees, and other costs and expenses incurred in connection with the merger agreement and the transactions contemplated in the merger agreement, will be paid by the party incurring such expenses. WesBanco will pay all governmental and regulatory authority fees incurred in connection with the transactions contemplated by the merger agreement.

Termination Fee

The merger agreement provides that ESB may be required to pay a termination fee to WesBanco of $11,354,000 in the following circumstances:

• If WesBanco terminates the merger agreement because (A) ESB’s board of directors (1) has modified, qualified, withheld or withdrawn its recommendation to the ESB shareholders that they vote to approve the merger, or made any statement, filing or release, in connection with the special meeting of ESB shareholders or otherwise, that was inconsistent with such recommendation, (2) breached its obligations to call, give notice of and commence the special meeting of ESB shareholders, (3) approved or recommended an Acquisition Proposal, (4) failed to publicly recommend against a publicly announced Acquisition Proposal within ten business days of being requested to do so by WesBanco, (5) failed to publicly reconfirm its recommendation to the ESB shareholders that they vote to approve the merger within ten business days of being requested to do so by WesBanco, or (6) resolved or otherwise determined to take, or announced an intention to take, any of the foregoing actions, or (B) ESB has materially breached its representation and warranty to recommend adoption of the merger agreement by ESB shareholders;

• If ESB terminated the merger agreement in order to enter into an agreement with a third party with respect to a superior proposal (as defined in the merger agreement);

• If (A) the merger agreement is terminated by either party because the merger has not been completed by July 31, 2015 or because the ESB shareholders failed to adopt the merger agreement at the special meeting of ESB’s shareholders, (B) an Acquisition Proposal with respect to ESB was publicly announced, disclosed or communicated to ESB’s board of directors prior to July 31, 2015 and the special meeting of ESB shareholders, and (C) within 12 months of such termination, ESB consummates an Acquisition Transaction or enters into any definitive agreement with respect to an Acquisition Transaction; or

• If (A) prior to the effective date of the merger ESB had committed a material breach of any of its representations, warranties, covenants or agreements, (B) an Acquisition Proposal with respect to ESB was publicly announced, disclosed or communicated to ESB’s board of directors prior to such breach by ESB or during the 30-day cure period resulting in termination of the merger agreement by WesBanco, and (C) within 12 months of such termination, ESB consummates an Acquisition Transaction or enters into any definitive agreement with respect to an Acquisition Transaction.

As defined in the merger agreement, “Acquisition Proposal” means any inquiry, offer or proposal (other than an inquiry offer or proposal from WesBanco), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction.

Removal of Directors; Filling Vacancies on the Board of Directors

ESB’s articles of incorporation provide that any director may be removed from office without cause by the affirmative vote of not less than 75% of the total votes eligible to be cast by shareholders at a duly constituted meeting of shareholders called expressly for such purpose and may be removed from office with cause by the affirmative vote of not less than a majority of the total votes eligible to be cast by shareholders. ESB’s articles of incorporation provide that vacancies on the board of directors shall be filled by a majority vote of the directors then in office, whether or not a quorum is present, or by a sole remaining director.

Under the WVBCA, the shareholders may remove one or more directors with or without cause, but only at a meeting called for the purpose of removing the director(s) and the meeting notice must state that the purpose, or one of the purposes, of the meeting is removal of the director(s). The director(s) may be removed by the shareholders only by the affirmative vote of a majority of all of the votes entitled to be cast. However, a director may not be removed if the number of votes sufficient to elect the director under cumulative voting is voted against his or her removal. WesBanco’s bylaws provide that the shareholders may remove any elected director for cause and fill the vacancy created. Any vacancy not caused by a shareholder removal may be filled by the remaining board members.

Cumulative Voting

Cumulative voting entitles each shareholder to cast an aggregate number of votes equal to the number of voting shares held, multiplied by the number of directors to be elected. Each shareholder may cast all of his or her votes for one nominee or distribute them among two or more nominees. The candidates (up to the number of directors to be elected) receiving the highest number of votes are elected.

Pursuant to ESB’s articles of incorporation, ESB shareholders are prohibited from cumulating their votes for the election of directors.

Under the WVBCA and WesBanco’s articles of incorporation, WesBanco shareholders are entitled to cumulative voting in the election of directors.

Indemnification of Officers and Directors

Under the PBCL, unless otherwise restricted in its bylaws, a corporation has the power to indemnify any person who was or is a party or threatened to be made a party to any threatened, pending, or completed action or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of the

- 99 -

corporation), by reason of the fact that the person is or was a representative of the corporation, or is or was serving at the request of the corporation as a representative of another domestic or foreign corporation for profit or not-for-profit, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by the person in connection with the action or proceeding if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. Further, a corporation may pay expenses incurred in defending any action or proceeding in advance of the final disposition of action upon receipt of an undertaking by or on behalf of the representative to repay the amount if it is ultimately determined that the representative is not entitled to indemnification from the corporation.

Under the PBCL, the statutory provisions for indemnification and advancement of expenses are not deemed to be exclusive of any other rights to which a person seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, or vote of shareholders or disinterested directors. A corporation may establish a fund to secure or insure in any manner its indemnification obligations. However, indemnification is prohibited in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness.

Under the PBCL, unless otherwise restricted in its bylaws, a corporation may purchase and maintain insurance on behalf of any person who is or was a representative of the corporation or is or was serving at the request of the corporation as a representative of another domestic or foreign corporation for profit or not-for-profit, partnership, joint venture, trust, or other enterprise against any liability asserted against him in any such capacity or arising out of his status as such, whether or not the corporation would have the power to indemnify him against that liability.

ESB’s articles of incorporation provide that ESB will indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit, or proceeding, including actions by or in the right of ESB, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director, officer, employee or agent of ESB, or is or was serving at the request of ESB as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys’ fees), judgments, fines, excise taxes, and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding to the full extent permissible under Pennsylvania law. ESB’s articles of incorporation also provide that advances of reasonable expenses may be paid to a director, officer, or employee or agent of ESB in defending a civil or criminal action, suit or proceeding in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such person to repay the advance if it is ultimately determined that the person is not entitled to be indemnified by ESB.

ESB’s articles of incorporation provide that ESB may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of ESB, or is or was serving at the request of ESB as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not ESB would have the power to indemnify such person against such liability. Pursuant to ESB’s articles of incorporation, ESB’s board of directors may enter into agreements with its officers, directors, employees and agents for the purpose of securing or insuring in any manner ESB’s obligation to indemnify or advance expenses.

Under the WVBCA, a corporation is generally permitted to indemnify a director if the director conducted himself or herself in good faith, he or she reasonably believed the conduct to be in the best interests of the corporation (or at least not opposed to the best interests of the corporation for all conduct that was not in his or her official capacity), and, in the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. In addition, the WVBCA permits a corporation to include broader indemnification in its articles of incorporation so long as the provision does not limit the liability for (i) receipt of a financial benefit to which he or she is not entitled, (ii) an intentional infliction of harm on the corporation or its shareholders, (iii) certain unlawful distributions, or (iv) an intentional violation of criminal law. The articles of incorporation

- 100 -

may also contain a provision (the “elimination provision”) eliminating or limiting the personal liability of a director to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director so long as the provision does not eliminate or limit the liability of a director for (i) any breach of the director’s duty of loyalty to the corporation or its shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct of a knowing violation of law, (iii) certain unlawful distributions, or (iv) any transaction from which the director derived an improper personal benefit. The elimination provision may not apply to conduct occurring prior to the provision’s adoption. The WVBCA requires a corporation to indemnify a director, who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he or she was a party because he or she was a director of the corporation, against reasonable expenses incurred by him or her in connection with the proceeding.

The WVBCA permits a corporation to advance funds to pay for or reimburse the reasonable expenses incurred by a director, prior to the final disposition of a proceeding, who is a party to a proceeding because he or she is a director, if he or she delivers to the corporation:

A WRITTEN AFFIRMATION OF HIS OR HER GOOD FAITH BELIEF THAT HE OR SHE HAS MET THE RELEVANT STANDARD OF CONDUCT DESCRIBED IN THE FIRST SENTENCE OF THE PRECEDING PARAGRAPH OR THAT THE PROCEEDING INVOLVES CONDUCT FOR WHICH LIABILITY HAS BEEN ELIMINATED UNDER THE ELIMINATION PROVISION; AND

A WRITTEN UNDERTAKING TO REPAY ANY FUNDS ADVANCED IF HE OR SHE IS NOT ENTITLED TO MANDATORY INDEMNIFICATION AND IT IS ULTIMATELY DETERMINED THAT HE OR SHE HAS NOT MET THE RELEVANT STANDARD OF CONDUCT.

The WVBCA provides that a corporation may indemnify its officers to the same extent as a director and, if the officer is not a director or if the officer is a party to the proceeding solely in his capacity as an officer, to a further extent as may be provided in the articles of incorporation, the bylaws, a resolution of the board of directors, or a contract, except that such additional indemnification may not be provided for liability in connection with a proceeding by or in the right of the corporation other than for reasonable expenses incurred in connection with the proceeding or liability arising out of conduct that constitutes (i) receipt by him or her of a financial benefit to which he or she is not entitled, (ii) an intentional infliction of harm on the corporation or the shareholders, or (iii) an intentional violation of criminal law. The WVBCA mandates indemnification of officers that are not directors to the same extent as directors.

WesBanco’s bylaws provide that WesBanco will indemnify each of its directors and officers, whether or not then in office, against all costs and expenses reasonably incurred in connection with any suit to which he is a party by reason of having been an officer or director of WesBanco or another company which he served at the request of WesBanco to the maximum extent permitted under the WVBCA and unless he is adjudged derelict in the performance of his duties as director or officer. Additionally, the WesBanco bylaws provide that a director or officer shall not receive a “prohibited indemnification payment,” which is defined as any payment or agreement to make a payment or reimburse such director or officer for any liability or legal expenses in any administrative proceeding brought by the appropriate federal banking agency that results in a final order or settlement in which the director or officer is assessed a civil monetary penalty, is removed or prohibited from conducting the business of banking, or is required to cease an action or take any affirmative action, including making restitution, with respect to WesBanco Bank, Inc. or WesBanco. Finally, WesBanco’s bylaws provide that a reasonable indemnification payment will be made only if all of the following conditions are met: (i) the board of directors investigates and determines in writing that the director or officer acted in good faith and in the best interest of WesBanco Bank, Inc. or WesBanco; (ii) the board of directors investigates and determines that the payment will not materially adversely affect the safety and soundness of WesBanco Bank, Inc. or WesBanco; (iii) the payment does not fall within the definition of a prohibited indemnification payment; and (iv) the director or officer agrees in writing to reimburse WesBanco, to the extent not covered by permissible insurance, for advanced indemnification payments that subsequently become prohibited indemnification payments.

- 101 -

WesBanco’s bylaws provide that WesBanco may purchase commercial insurance to cover certain costs that WesBanco incurs under the indemnification provisions. Costs that may be covered include legal expenses and restitution that an individual may be ordered to make to WesBanco. Such insurance may not pay or reimburse a director or officer for any final judgment or civil money penalty assessed against such individual. Partial indemnification for legal expenses is permitted in connection with a settlement when there is a formal and final finding that the director or officer has not breached a fiduciary duty, engaged in unsafe or unsound practices, and is not subject to a final prohibition order.

Amendment of Articles of Incorporation and Bylaws

ESB’s articles of incorporation may be amended after the amendment is first approved by the board of the directors pursuant to a resolution adopted by the affirmative vote of a majority of the directors then in office, and thereafter is approved by the holders of a majority of shares entitled to vote generally in an election of directors, voting together as a single class, as well as such additional vote of the preferred stock as may be required by the provisions of any such series. However, (i) the affirmative vote of the holders of at least 75% of the shares as a single class, as well as such additional vote of the preferred stock as may be required, shall be required to amend, adopt, alter, change, or repeal any provision inconsistent with certain enumerated articles.

ESB’s bylaws may be amended by (i) acquiring the affirmative vote of a majority of the directors then in office at any regular or special meeting of the board of directors, or (ii) acquiring the affirmative vote of the holders of a majority of shares entitled to vote generally in an election of directors, voting together as a single class, as well as such additional vote of the preferred stock as may be required, provided that the affirmative vote of the holders of at least 75% of the shares entitled to vote generally in an election of directors, voting together as a single class, as well as such additional vote of the preferred stock as may be required, shall be required to amend, adopt, alter, change, or repeal any provision inconsistent with certain sections and articles of the bylaws.

Pursuant to the WVBCA, the WesBanco articles of incorporation and bylaws may generally be amended by the affirmative vote of a majority of all votes of shareholders entitled to be cast on the matter amendment and a majority of the outstanding stock of each class entitled to vote on the amendment, unless a greater number is specified in the articles of incorporation. The WesBanco articles of incorporation provide that the affirmative vote of the holders of not less than 75% of the outstanding shares of the voting stock is required to amend, alter, change, or repeal the article section dealing with the classes of directors.

WesBanco’s bylaws require the affirmative vote of the holders of not less than 75% of the outstanding shares of the capital stock to amend or repeal the bylaw provisions dealing with the composition of the board of directors. The other bylaw provisions may be amended, altered, or repealed (i) at any duly called and constituted shareholders’ meeting on the affirmative vote of the majority of the stock represented at such meeting, or (ii) at any meeting of the board of directors upon the affirmative vote of the majority of the whole of the board.

Under the PBCL, certain anti-takeover provisions apply to Pennsylvania registered corporations (e.g., publicly traded companies) including those relating to (i) control share acquisitions, (ii) disgorgement of profits by certain controlling persons, (iii) business combination transactions with interested shareholders, and (iv) the rights of shareholders to demand fair value for their stock following a control transaction. The PBCL allows corporations to opt out of these anti-takeover provisions. As such, ESB has opted out of the provisions relating to items (i) through (iii) above. A general summary of the anti-takeover provisions is set forth below.

Rights of Shareholders to Demand Fair Value Following Control Transaction. A shareholder who objects to a control transaction is entitled to demand to be paid the fair value of such shareholder’s shares. A control transaction for these purposes is the acquisition by a controlling person, as defined above for purposes of the “Disgorgement of Profits by Certain Controlling Persons.” Fair value may not be less than the highest price paid per share by the controlling person within the 90-day period ending on and including the date of the control

transaction, taking into account all relevant factors, including an increment representing a proportion of any value payable for acquisition of control of the corporation.

Neither the WVBCA nor WesBanco’s articles of incorporation or bylaws contain any provisions addressing interested shareholder transactions.

ADJOURNMENT PROPOSAL

The WesBanco Adjournment Proposal

In the event a quorum is present at the WesBanco special meeting but there are insufficient votes to approve the issuance of shares of WesBanco common stock in connection with the merger, that proposal will fail unless WesBanco adjourns the special meeting in order to solicit additional proxies from WesBanco shareholders. An adjournment under such circumstances will allow WesBanco extra time to solicit additional proxies. In order to allow shares present in person or by proxy at the WesBanco special meeting to vote FOR approval of the adjournment of the WesBanco special meeting, if necessary, WesBanco is submitting an adjournment of the WesBanco special meeting to you as a separate matter for consideration. WesBanco will vote properly submitted proxy cards FOR approval of the WesBanco adjournment proposal, unless otherwise indicated on the proxy. If WesBanco shareholders approve the WesBanco adjournment proposal, WesBanco is not required to give any further notice of the time and place of the adjourned WesBanco meeting other than an announcement of the time and place provided at the WesBanco special meeting.

If a quorum is not present at the WesBanco meeting, the WesBanco meeting will be adjourned to a later time without a vote.

Recommendation of WesBanco’s Board of Directors

WesBanco’s board of directors recommends that WesBanco shareholders vote FOR approval of the WesBanco adjournment proposal.

ESB SHAREHOLDERS — PROPOSAL NO. 2 —

ADVISORY (NON-BINDING) VOTE ON GOLDEN PARACHUTE COMPENSATION

The Golden Parachute Proposal

In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, ESB’s board of directors is providing ESB shareholders with the opportunity to cast an advisory vote on the “golden parachute” compensation payable to the named executive officers of ESB in connection with the merger at the special meeting through the following resolution:

“RESOLVED, that the compensation that may be paid or become payable to ESB named executive officers in connection with the merger, as disclosed in the table entitled “Golden Parachute Compensation” that begins on page [—], together with the accompanying footnotes and narrative discussion relating to the named executive officers’ golden parachute compensation and the agreements or understandings pursuant to which such compensation may be paid or become payable, as set forth in the section of this joint proxy statement/prospectus titled “WesBanco Proposal No. 1 (Approval of the Share Issuance) and ESB Proposal No. 1 (Adoption of the Merger Agreement) — Summary of Golden Parachute Arrangements” is hereby APPROVED.”

The vote on this Proposal 2 by ESB shareholders is a vote separate and apart from the vote on Proposal 1 by ESB shareholders to adopt the merger agreement. Accordingly, ESB shareholders may vote to approve this Proposal 2 and not to approve Proposal 1, and vice versa. Because the vote is advisory in nature only, it will not be binding on WesBanco, WesBanco Bank, ESB or ESB Bank regardless of whether the merger agreement is adopted. Accordingly, as the compensation to be paid in connection with the merger is contractual with the executives, regardless of the outcome of this advisory vote, such compensation will be paid, subject only to the conditions applicable to such payment and the merger being completed.

The named executive officers of ESB for which this advisory vote is being taken are Charlotte A. Zuschlag, President and Chief Executive Officer, Charles P. Evanoski, Group Senior Vice President and Chief Financial Officer, Frank D. Martz, Group Senior Vice President of Operations and Secretary, Todd F. Palkovich, Group Senior Vice President of Lending, and Richard E. Canonge, Group Senior Vice President of Audit, Compliance and Loan Review. This vote is not intended to address any specific item of compensation, but rather the overall compensation that may become payable to ESB’s named executive officers in connection with the completion of the merger transaction. Such compensation will not be payable in the event the merger is not completed.

Recommendation of ESB Board of Directors

ESB’s board of directors unanimously recommends that ESB shareholders vote FOR approval, on an advisory (non-binding) basis, of the golden parachute compensation payable to the named executive officers of ESB in connection with the merger.

In order to allow shares present in person or by proxy at the ESB special meeting to vote FOR approval of the adjournment of the ESB special meeting, if necessary, ESB is submitting an adjournment of the ESB special meeting to ESB shareholders as a separate matter for consideration. ESB will vote properly submitted proxy cards FOR approval of the ESB adjournment proposal, unless otherwise indicated on the proxy. If ESB shareholders approve the ESB adjournment proposal, ESB is not required to give any further notice of the time and place of the adjourned ESB meeting other than an announcement of the time and place provided at the ESB special meeting.

If a quorum is not present at the meeting, the meeting will be adjourned to a later time without a vote.

At the Effective Time, all Buyer Shares that are owned by Seller or any of its Subsidiaries (other than Trust Account Shares and DPC Shares) shall become treasury stock of Buyer without any consideration therefor.

(b) At or prior to the Effective Time, Seller, the Seller Board (as defined in Section 5.03(b)) and the compensation committee of such board, as applicable, shall adopt any resolutions and take any actions (including obtaining any Seller or Seller Sub employee consents) that may be necessary to effectuate the provisions of paragraph (a) of this Section 2.02.

2.03. Exchange and Payment Procedures

(a) Exchange Agent. Buyer shall designate Computershare Investor Services, LLC or such other entity as shall reasonably be selected by Buyer to act as agent (the “Exchange Agent”) for purposes of conducting the exchange and payment procedures as described in this Section 2.03. Seller shall provide to the Exchange Agent all information reasonably requested by Buyer to be provided to the Exchange Agent in order for it to perform as specified herein.

(b) Deposit with Exchange Agent; Exchange Fund. At least one business day prior to the Effective Time, Buyer shall provide to the Exchange Agent the aggregate number of Buyer Shares and an amount in cash representing the aggregate cash component of the Merger Consideration, together with aggregate cash to be paid in lieu of fractional shares pursuant to Section 2.03(f) hereto, all of which shall be held by the Exchange Agent in trust for the holders of Seller Shares (collectively, the “Exchange Fund”). The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the Buyer Shares held by it from time to time hereunder, except that it shall receive and hold for the benefit of the recipients of the Buyer Shares until distributed thereto pursuant to the provisions of this Agreement any dividends or other distributions paid or distributed with respect to such Buyer Shares for the account of the persons entitled thereto. The Exchange Fund shall not be used for any purpose other than as set forth in this paragraph. The Exchange Agent shall invest cash in the Exchange Fund, as directed by Buyer, on a daily basis; provided, however, that all such investments shall be in (1) obligations of, or guaranteed by, the United States of America, (2) commercial paper obligations receiving the highest rating from either Moody’s Investors Services, Inc. or Standard and Poor’s Corporation, or (3) certificates of deposit of commercial banks (not including any Subsidiary (as defined in Section 3.01(c)) or affiliate of Buyer) with capital exceeding $1.0 billion. All interest and other income resulting from such investments shall be paid to Buyer.

(c) Surrender of Seller Certificates. As promptly as practicable after the Effective Time, and in no event more than five business days thereafter, Buyer shall send or cause to be sent to each former holder of record of Seller Shares transmittal materials (which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing the Seller Shares shall pass only upon proper delivery of such certificates to the Exchange Agent). Each holder of an outstanding certificate or certificates which prior to the Effective Time represented Seller Shares (“Seller Certificate”), who surrenders such Seller Certificate to the Exchange Agent shall, upon acceptance thereof by the Exchange Agent, be entitled to receive (a) the Merger Consideration for each Seller Share represented by the Seller Certificate surrendered, (b) any cash in lieu of fractional shares into which the Seller Shares represented by the Seller Certificate have been converted, (c) any other dividend or distribution

A-4

with a record date after the Effective Time theretofore paid with respect to Buyer Shares issuable in the Merger, and (d) subject to compliance with Section 7.08, any dividend or distribution with respect to Seller Shares with a record date prior to the Effective Time, in each case without interest. The Exchange Agent shall accept such Seller Certificate upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices and shall as promptly as practicable issue the certificates representing Buyer Shares and cash in accordance with this Agreement. Each Seller Certificate that is not surrendered to the Exchange Agent in accordance with the procedures provided for herein shall, except as otherwise herein provided, be deemed at any time after the Effective Time to represent only the right to receive upon such surrender (a) the Merger Consideration, (b) any cash in lieu of fractional shares into which the Seller Shares represented by the Seller Certificate have been converted, (c) any other dividend or distribution with a record date after the Effective Time theretofore paid with respect to Buyer Shares issuable in the Merger, and (d) subject to compliance with Section 7.08, any dividend or distribution with respect to Seller Shares with a record date prior to the Effective Time, in each case without interest. No dividends or other distributions with a record date after the Effective Time with respect to Buyer Shares shall be paid to the holder of any unsurrendered Seller Certificate until the holder thereof shall surrender such Seller Certificate in accordance with this Section 2.03(c). After the surrender of a Seller Certificate in accordance with this Section 2.03(c), the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to Buyer Shares represented by such Seller Certificates. After the Effective Time, there shall be no further transfer on the records of Seller of a Seller Certificate representing Seller Shares and, if any such Seller Certificate is presented to Seller for transfer, it shall be canceled against delivery of the Merger Consideration for each Seller Share represented by such Seller Certificate provided in Article Two.

(d) Lost, Stolen or Destroyed Certificates. If there shall be delivered to the Exchange Agent by any person who is unable to produce any Seller Certificate for Seller Shares for surrender to the Exchange Agent in accordance with this Section 2.03:

(i) evidence to the reasonable satisfaction of the Surviving Corporation that such Seller Certificate has been lost, wrongfully taken, or destroyed;

(ii) such security or indemnity as reasonably may be requested by the Surviving Corporation to save it harmless (which may include the requirement to obtain a third party bond or surety); and

(iii) evidence, to the reasonable satisfaction of the Surviving Corporation, that such person was the owner of the Seller Shares theretofore represented by each such Seller Certificate claimed by him to be lost, wrongfully taken or destroyed and that he is the person who would be entitled to present such Seller Certificate for exchange pursuant to this Agreement;

then the Exchange Agent, in the absence of actual notice to it that any Seller Shares theretofore represented by any such Seller Certificate have been acquired by a bona fide purchaser, shall deliver to such person (a) the Merger Consideration for each Seller Share represented by the lost, stolen or destroyed Seller Certificate, (b) any cash in lieu of fractional shares into which the Seller Shares represented by the Seller Certificate have been converted, (c) any other dividend or distribution with a record date after the Effective Time theretofore paid with respect to Buyer Shares issuable in the Merger, and (d) subject to compliance with Section 7.08, any dividend or distribution with respect to Seller Shares with a record date prior to the Effective Time, in each case without interest, that such person would have been entitled to receive upon surrender of each such lost, wrongfully taken or destroyed Seller Certificate.

(e) No Further Ownership Rights in Seller Shares. All cash and Buyer Shares issued upon conversion of Seller Shares in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such Seller Shares; subject, however, to the Surviving Corporation’s obligation to pay any dividends or make any other distributions with a record date prior

A-5

to the Effective Time which may have been declared or made by Seller (but only in compliance with the terms of this Agreement) on such Seller Shares prior to the Effective Time and which remain unpaid at the Effective Time, subject to compliance with Section 7.08.

(f) No Fractional Buyer Shares.

(i) No certificates or scrip representing fractional Buyer Shares shall be issued upon the surrender for exchange of Seller Certificates evidencing Seller Shares, and such fractional Buyer Share interests will not entitle the owner thereof to vote or to any rights of a shareholder of the Surviving Corporation.

(ii) Each holder of Seller Shares who would otherwise be entitled to receive a fractional Buyer Share shall instead receive from the Exchange Agent an amount of cash, without interest, equal to the product obtained by multiplying (a) the fractional Buyer Share (rounded to the nearest thousandth when expressed in decimal form) interest to which such holder (after taking into account all Seller Shares held at the Effective Time by such holder) would otherwise be entitled by (b) the Average Closing Price (as defined in Section 11.01(d)(iv)).

(g) Termination of Exchange Fund. Any portion of the Exchange Fund delivered to the Exchange Agent by Buyer pursuant to Section 2.03(b) which remains undistributed to the shareholders of Seller for 12 months after the Effective Time may be delivered to the Surviving Corporation, upon Buyer’s demand, and any shareholders of Seller who have not theretofore complied with this Article Two shall thereafter look only to the Surviving Corporation for payment of the Merger Consideration, any cash in lieu of fractional Buyer Share interest and any dividends or distributions with respect to Buyer Shares issuable in the Merger, in each case without interest.

(h) No Liability. None of Buyer, Seller, the Exchange Agent or the Surviving Corporation shall be liable to any former holder of Seller Shares for any payment of the Merger Consideration, any cash in lieu of fractional Buyer Share interest or any dividends or distributions with respect to Buyer Shares issuable in the Merger delivered to a public official as and if required by any applicable abandoned property, escheat or similar law.

(i) Withholding Rights. Buyer or the Exchange Agent shall be entitled to deduct and withhold from the cash consideration otherwise payable pursuant to this Agreement to any holder of Seller Certificates such amounts as Buyer or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any other provision of domestic or foreign (whether national, Federal, state, provincial, local or otherwise) tax law. To the extent that amounts are properly withheld and paid over to the appropriate taxing authority by Buyer or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Seller Certificates in respect of which such deduction and withholding was made by Buyer, the Surviving Corporation or the Exchange Agent.

(j) Waiver. The Surviving Corporation may from time to time, in the case of one or more persons, waive one or more of the rights provided to it in this Article Two to withhold certain payments, deliveries and distributions; and no such waiver shall constitute a waiver of its rights thereafter to withhold any such payment, delivery or distribution in the case of any person.

2.04. No Dissenters’ Rights

Anything contained in this Agreement or elsewhere to the contrary notwithstanding, no outstanding Seller Shares or other shares of Seller’s capital stock shall have any dissenters’ rights of appraisal under the PBCL.

2.05. Anti-Dilution Provisions

In the event that, subsequent to the date of this Agreement but prior to the Effective Time, the outstanding Buyer Shares are increased, decreased, changed into or exchanged for a different number or kind of shares or

A-6

securities (or Buyer establishes a record date for effecting any such change to the outstanding Buyer Shares) as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar changes in Buyer’s capitalization, excluding an acquisition by Buyer involving an exchange of Buyer Shares not resulting in a recapitalization of Buyer, appropriate and proportionate adjustment shall be made to the Merger Consideration. Nothing contained herein shall be deemed to permit any action which may be proscribed by this Agreement.

2.06. Conversion of Seller Sub Capital Stock

Immediately after the Effective Time, each issued and outstanding share, and each share held in the treasury, of capital stock of Seller Sub shall, by virtue of the Bank Merger and without any action on the part of Buyer, Buyer Sub, Seller, Seller Sub or the holder thereof, be canceled without any conversion or issuance of any shares of capital stock of Buyer or Buyer Sub with respect thereto. No shares of Buyer or Buyer Sub shall be issued or exchanged and no consideration shall be given for shares of Seller Sub, and each then-issued and outstanding share, and each share then held in the treasury, of capital stock of Buyer Sub shall, by virtue of the Bank Merger and without any action on the part of Buyer, Buyer Sub, Seller, Seller Sub or the holder thereof, continue as one share of capital stock of the Surviving Bank Corporation having the same designations, preferences, limitations, and rights as such share of capital stock of Buyer Sub immediately prior to the Bank Merger.

(ii) Seller Sub, ESB Capital Trust IV and THF, Inc. are the only Subsidiaries (as that term is defined in Section 3.01(c)) of Seller, and, except as set forth in Section 3.01(a)(ii) of the Seller Disclosure Schedule, AMSCO, Inc. and ESB Financial Services, Inc. are the only Subsidiaries of Seller Sub (each, a “Seller Subsidiary” and collectively, the “Seller Subsidiaries”).

A-7

otherwise, to own its property and to carry on its business as presently conducted, and is qualified to do business and in good standing in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification necessary, except where the failure to be so qualified or in good standing would not have a material adverse effect on Seller. Seller has made available to Buyer true and complete copies of the governing instruments of Seller Sub, in each case as amended to the date of this Agreement.

(iii) Each of the Seller Subsidiaries other than Seller Sub has been duly organized and is validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified or licensed to do business and is in good standing in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification necessary, other than where the failure to be so organized, existing, qualified or licensed or in good standing, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Seller.

(iv) As used in this Agreement, (A) any reference to any event, change or effect being “material” with respect to any entity means an event, change or effect which is material in relation to the financial condition, properties, business or results of operations of such entity and its Subsidiaries taken as a whole and (B) the terms “material adverse effect” or “material adverse change” means, with respect to an entity, a material adverse effect on the financial condition, properties, assets, liabilities, businesses or results of operations of such entity and its Subsidiaries taken as a whole or on the ability of such entity to perform its obligations under this Agreement or consummate the Merger or the Bank Merger and the other material transactions contemplated by this Agreement other than, in any case, any state of facts, change, development, event, effect, condition or occurrence (i) resulting from changes in the United States economy (including changes in interest rates) or the United States securities markets in general; (ii) resulting from changes in laws or regulations affecting banks or savings banks or their holding companies generally, or interpretations thereof by Governmental Authorities; (iii) resulting from any litigation or loss of current or prospective customers, employees or revenues arising from the execution of this Agreement; (iv) resulting from any transaction costs of the Merger generally; (v) resulting from payments made in the nature of severance payments or payments made pursuant to the change in control provisions of employment agreements or change in control or severance plans of Seller or any Seller Subsidiary or payments made pursuant to Section 6.02(b) or losses, charges or expenses resulting from loan sales contemplated by Section 5.09; (vi) resulting from changes, after the date hereof, in accounting principles generally accepted in the United States (“GAAP”) or applicable regulatory accounting requirements; (vii) resulting from changes, after the date hereof, in global, national or regional political conditions (including events of war or acts of terrorism); or (viii) resulting from public disclosure of the transactions contemplated hereby or actions that are expressly required by this Agreement or that are taken with the prior written consent of the other party in contemplation of the transactions contemplated hereby; provided, however, that in no event shall a decrease in the trading price of Seller Shares or Buyer Shares, absent any other event, change or effect which has had or would reasonably be expected to have a material adverse effect, or litigation relating thereto, be considered a material adverse effect or material adverse change; and provided, further, that any state of facts, change, development, event, effect, condition or occurrence referred to in clauses (i), (ii), (vi) or (vii) immediately above shall be taken into account in determining whether a material adverse effect or material adverse change has occurred to the extent that such state of facts, change, development, event, effect, condition or occurrence has a disproportionate effect on Seller or Buyer, as the case may be, compared to other similarly situated community banking organizations operating in the geographic regions in which the Seller or Buyer, as the case may be, conduct their business.

(g) SEC Filings; Sarbanes-Oxley.

(i) Seller and the Seller Subsidiaries have filed all reports, registration statements, proxy statements and information statements required to be filed by Seller or any of the Seller Subsidiaries subsequent to December 31, 2010 under the Securities Act of 1933, as amended (the “Securities Act”), or under Sections 13(a), 13(c), 14 and 15(d) of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”) with the SEC (together with all information incorporated therein by reference, the “Seller SEC Documents”), except for any reports, registration statements, proxy statements or information statements the failure to file which would not have a material adverse effect upon Seller. All such filings, at the time of filing, complied in all material respects as to form and included all exhibits required to be filed under the applicable rules of the SEC applicable to such Seller SEC Documents. None of such documents, as subsequently supplemented or amended prior to the date hereof, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(ii) The records, systems, controls, data and information of Seller and the Seller Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership and direct control of Seller or the Seller Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership and non-direct control that would not reasonably be expected to have a material adverse effect on Seller. Seller (x) has implemented and maintains disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) to ensure that material information relating to Seller, including its consolidated Subsidiaries, is made known to the chief executive officer and the chief financial officer of Seller by others within those entities, and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to Seller’s outside auditors and the audit committee of the Seller Board (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to adversely affect Seller’s ability to record, process, summarize and report financial information, and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Seller’s internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). These disclosures were made in writing by management to Seller’s auditors and audit committee and a copy has previously been made available to Buyer. As of the date hereof, there is no reason to believe that Seller’s chief executive officer and chief financial officer will not be able to give the certifications and attestations required pursuant to the rules and regulations adopted pursuant to Section 404 of the Sarbanes-Oxley Act, without qualification, when next due.

(iii) Since December 31, 2010, (i) through the date hereof, neither Seller nor any of the Seller Subsidiaries has received or otherwise had or obtained actual knowledge of any material complaint, allegation, assertion or claim, whether written or oral, regarding the accounting or auditing practices, procedures, methodologies or methods of Seller or any of the Seller Subsidiaries or their respective internal accounting controls, including any material complaint, allegation, assertion or claim that Seller or any of the Seller Subsidiaries has engaged in questionable accounting or auditing practices, and (ii) no attorney representing Seller or any of the Seller Subsidiaries, whether or not employed by Seller or any of the Seller Subsidiaries, has reported evidence of a material violation of securities laws, breach of fiduciary duty or similar violation by Seller or any of its officers, directors, employees or agents to the Seller Board or any committee thereof or to any director or officer of Seller.

S.R. Snodgrass, A.C. has not resigned or been dismissed as an independent public accountant of Seller as a result of or in connection with any disagreement with Seller on a matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure.

(v) Since the date of Seller’s last definitive proxy statement for its annual meeting of its shareholders and except as disclosed in Section 3.01(g) of the Seller Disclosure Schedule, no event has occurred that would be required to be reported by the Seller pursuant to Item 404 of Regulation S-K promulgated by the SEC.

(h) Absence of Undisclosed Liabilities. Except as set forth in the Seller SEC Documents filed and publicly available prior to the date of this Agreement (the “Seller Filed SEC Documents”) (including the financial statements included therein) or in Section 3.01(h) of the Seller Disclosure Schedule and except as arising hereunder, Seller and the Seller Subsidiaries have no liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) at June 30, 2014, other than liabilities and obligations that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Seller. Except as set forth in the Seller Filed SEC Documents or otherwise disclosed in Section 3.01(h) of the Seller Disclosure Schedule, all debts, liabilities, guarantees and obligations of Seller and the Seller Subsidiaries incurred since the Seller Balance Sheet Date have been incurred in the ordinary course of business and are usual and normal in amount, both individually and in the aggregate.

(j) Loan Documentation. The documentation (“Loan Documentation”) governing or relating to the material loan and credit-related assets (“Loan Assets”) included in the loan portfolio of the Seller Subsidiaries is legally sufficient for the purposes intended thereby and creates enforceable rights of the Seller Subsidiaries in accordance in all material respects with the terms of such Loan Documentation, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws relating to or affecting the enforcement of creditors’ rights generally, by general equitable principles (regardless of whether enforceability is considered in a proceeding in equity or at law) and by an implied covenant of good faith and fair dealing, except for such insufficiencies as would not have a material adverse effect on Seller. Except as set forth in Section 3.01(j) of the Seller Disclosure Schedule, no debtor under any of the Loan Documentation has asserted as of the date hereof any claim or defense with respect to the subject matter thereof, which claim or defense, if determined adversely to Seller, would have a material adverse effect on Seller. All loans and extensions of credit that have been made by the Seller Subsidiaries comply in all material respects with applicable regulatory limitations and procedures.

(k) Loans; Nonperforming and Classified Assets.

(i) To Seller’s knowledge, except as would not reasonably be expected to have a material adverse effect on Seller, each loan agreement, note or borrowing arrangement, including, without limitation, portions of outstanding lines of credit, loan commitments and loan guaranties (collectively, “Loans”), on Seller’s or any Seller Subsidiary’s books and records, was made and has been serviced in accordance with Seller’s lending standards in the ordinary course of business; is evidenced by appropriate and sufficient documentation; to the extent secured, has been secured by valid liens and security interests which have been perfected; and constitutes the legal, valid and

A-12

binding obligation of the obligor named therein, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws relating to or affecting the enforcement of creditors’ rights generally, and by general equitable principles (regardless of whether enforceability is considered in a proceeding in equity or at law). Seller has previously made available to Buyer complete and correct copies of its and the Seller Subsidiaries’ lending policies. The deposit and loan agreements of Seller and each Seller Subsidiary comply in all material respects with all applicable laws, rules and regulations. The allowance for loan losses reflected in the Seller SEC Documents and financial statements filed therewith, as of their respective dates, is adequate under all regulatory requirements applicable to Seller or Seller Sub.

All Loans which are classified as “Insider Transactions” by Regulation O of the Board of Governors of the Federal Reserve System (“Federal Reserve”) have been made by Seller or any of the Seller Subsidiaries in an arms-length manner made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons and do not involve more than normal risk of collectability or present other unfavorable features.

(iii) Seller shall reasonably promptly after the end of each quarter after the date hereof and upon Closing (as defined in Section 9.01) inform Buyer of the amount of Loans subject to each type of classification of the Classified Loans.

Seller and the Seller Subsidiaries have filed all reports and maintained all records required to be filed or maintained by them under the rules and regulations of the Federal Reserve, the PA DOB, the FDIC and the Federal Home Loan Bank of Pittsburgh (the “FHLB”), except for such reports and records the failure to file or maintain would not have a material adverse effect on Seller. All such documents and reports complied in all material respects with applicable requirements of law and rules and regulations in effect at the time such documents and reports were filed and contained in all material respects the information required to be stated therein, except for such documents and records the failure to comply with such laws, rules and regulations or contain such information would not have a material adverse effect on Seller. None of such documents or reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, other than such reports and documents which the failure to file in such fashion would not have a material adverse effect on Seller. There is no material unresolved violation, criticism or exception by any Governmental Authority or Regulatory Authority with respect to any report or letter relating to any examinations of Seller or any of the Seller Subsidiaries.

(m) Taxes. Except as set forth in Section 3.01(m) of the Seller Disclosure Schedule, Seller and the Seller Subsidiaries have timely filed (including all applicable extensions) all material returns, statements, reports and forms (including elections, declarations, disclosures, schedules, estimates and information returns) (collectively, the “Tax Returns”) with respect to all material Federal, state, local and foreign income, gross income, gross receipts, gains, premium, sales, use, ad valorem, transfer, franchise, profits, withholding, payroll, employment, excise, severance, stamp, occupancy, license, lease,

A-13

environmental, customs, duties, property, windfall profits and other taxes (including any interest, penalties or additions to tax with respect thereto, individually, a “Tax” and, collectively, “Taxes”) required to be filed with the appropriate tax authority through the date of this Agreement. Such Tax Returns, as amended, are true, correct and complete in all material respects. Seller and the Seller Subsidiaries have paid and discharged all Taxes shown as due on such Tax Returns, other than such Taxes that are adequately reserved as shown on the Seller Financial Statements or have arisen in the ordinary course of business since the Seller Balance Sheet Date. Except as set forth in Section 3.01(m) of the Seller Disclosure Schedule, neither the Internal Revenue Service (the “IRS”) nor any other taxing agency or authority, domestic or foreign, has asserted, is now asserting or, to the actual knowledge of Seller, is threatening to assert against Seller or any Seller Subsidiary any deficiency or claim for additional Taxes. There are no unexpired waivers by Seller or any Seller Subsidiary of any statute of limitations with respect to Taxes. The accruals and reserves for Taxes reflected in the Seller Financial Statements are adequate in all material respects for the periods covered. Seller and the Seller Subsidiaries have withheld or collected and paid over to the appropriate Governmental Authorities or are properly holding for such payment all Taxes required by law to be withheld or collected, except for such failures to withhold or collect as would not have a material adverse effect on Seller. There are no liens for Taxes upon the assets of Seller or any Seller Subsidiary, other than liens for current Taxes not yet due and payable and liens that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Seller. Neither Seller nor any Seller Subsidiary has agreed to make, or is required to make, any adjustment under Section 481(a) of the Code. Except as set forth in Section 3.01(m) of the Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary is a party to any agreement, contract, arrangement or plan that has resulted, or could result, individually or in the aggregate, in the payment of “excess parachute payments” within the meaning of Section 280G of the Code. Except as set forth in Section 3.01(m) of the Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary has ever been a member of an affiliated group of corporations, within the meaning of Section 1504 of the Code, other than an affiliated group of which Seller is or was the common buyer corporation. No Tax is required to be withheld pursuant to Section 1445 of the Code as a result of the transactions contemplated by this Agreement.

(n) Property and Title. Section 3.01(n) of the Seller Disclosure Schedule lists and describes all real property, and any leasehold interest in real property, owned or held by Seller or the Seller Subsidiaries and used in the business of Seller and the Seller Subsidiaries (collectively, the “Seller Real Properties”). The Seller Real Properties constitute all of the material real property and interests in real property used in the businesses of Seller and the Seller Subsidiaries. Copies of all leases of Seller Real Properties to which Seller or any Seller Subsidiary is a party have been provided to Buyer. The leasehold interests subject to such leases have not been assigned or subleased. All Seller Real Properties which are owned by Seller or any Seller Subsidiary are free and clear of all mortgages, liens, security interests, defects, encumbrances, easements, restrictions, reservations, conditions, covenants, agreements, encroachments, rights of way and zoning laws, except (i) those set forth in Section 3.01(n) of the Seller Disclosure Schedule; (ii) easements, restrictions, reservations, conditions, covenants, rights of way, zoning laws and other defects and irregularities in title and encumbrances which do not materially impair the use thereof for the purposes for which they are held; (iii) the lien of current taxes not yet due and payable and (iv) other defects in title, easements, restrictive covenants and similar encumbrances that, individually or in the aggregate, would not have a material adverse effect on Seller. Seller and the Seller Subsidiaries own, and are in rightful possession of, and have good title to, all of the other material assets used by Seller or any Seller Subsidiary in the conduct of their respective businesses (except for such assets that are leased by Seller or any Seller Subsidiary), free and clear of any charge, mortgage, pledge, security interest, hypothecation, restriction, claim, option, lien, encumbrance or interest of any persons whatsoever except for (i) those described in Section 3.01(n) of the Seller Disclosure Schedule, (ii) those assets disposed of in the ordinary course of business consistent with past practices, (iii) such as are no longer used or useful in the conduct of its businesses and (iv) defects in title, easements, restrictive covenants and similar encumbrances that, individually or

A-14

in the aggregate, would not have a material adverse effect on Seller. The assets of Seller and the Seller Subsidiaries, taken as a whole, are adequate to continue to conduct the businesses of Seller and the Seller Subsidiaries as such businesses are presently being conducted. To Seller’s actual knowledge, there are no applicable laws, conditions of record, or other impediments that materially interfere with the intended use by Seller or the Seller Subsidiaries of any of the Seller Real Properties.

(o) Legal Proceedings. Except as set forth in the Seller Filed SEC Documents or Section 3.01(o) of the Seller Disclosure Schedule, there are no actions, suits, proceedings, claims or investigations pending or, to the knowledge of Seller and the Seller Subsidiaries, threatened in any court, before any Governmental Authority or in any arbitration proceeding (i) against Seller or any Seller Subsidiary which, if adversely determined against Seller or any Seller Subsidiary, could have a material adverse effect on Seller or Seller Sub; or (ii) against or by Seller or any Seller Subsidiary which, if adversely determined against Seller or any Seller Subsidiary, could prevent the consummation of this Agreement or any of the transactions contemplated hereby or declare the same to be unlawful or cause the rescission thereof.

Neither Seller nor any Seller Subsidiary has been advised by any of the Regulatory Authorities that any of such Regulatory Authorities are contemplating issuing or requesting (or are considering the appropriateness of issuing or requesting) any such order, judgment, decree, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on Seller. Seller Subsidiary is “well-capitalized” (as that term is defined in 12 C.F.R. 325.103(b)(1)).

Except as disclosed in Section 3.01(q) of the Seller Disclosure Schedule and subject to the required adoption of this Agreement by the Required Seller Vote and approval of the issuance of the Buyer shares under this Agreement by the Required Buyer Vote, the receipt of the required approvals of Regulatory Authorities and Governmental Authorities, the expiration of applicable regulatory waiting periods and the required filings under Federal and state securities laws, the execution, delivery and performance of this Agreement, and the consummation of the transactions contemplated hereby by Seller and Seller Sub do not and will not (i) conflict with, or result in a violation of, or result in the breach of or a default (or which with notice or lapse of time would result in a default) under, any provision of: (A) any Federal, state or local law, regulation, ordinance, order, rule or administrative ruling of any administrative agency or commission or other Federal, state or local governmental authority or instrumentality (each, a “Governmental Authority”) applicable to Seller or Seller Sub or any of their respective properties; (B) the Articles of Incorporation or Bylaws of Seller, or the governing instruments of Seller Sub; (C) any material agreement, indenture or instrument to which Seller or Seller Sub is a party or by which it or its properties or assets may be bound; or (D) any order, judgment, writ, injunction or decree of any court, arbitration panel or any Governmental Authority applicable to Seller or Seller Sub, other than, in the case of clauses (A), (C) and (D), any such conflicts, violations, breaches or defaults that, individually or in the aggregate, would not have a material adverse effect on Seller; (ii) result in the creation or acceleration of any security interest, mortgage, option, claim, lien, charge or encumbrance upon or interest in any property of Seller or any of the Seller Subsidiaries, other than such security interests, mortgages, options, claims, liens, charges or

A-15

encumbrances that, individually or in the aggregate, would not have a material adverse effect on Seller; or (iii) violate the terms or conditions of, or result in the cancellation, modification, revocation or suspension of, any material license, approval, certificate, permit or authorization held by Seller or any of the Seller Subsidiaries, other than such violations, cancellations, modifications, revocations or suspensions that, individually or in the aggregate, would not have a material adverse effect on Seller.

(s) Employment Agreements. Except as disclosed in Section 3.01(s) of the Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary is a party to any employment, change in control, severance or consulting agreement not terminable at will by Seller or such Seller Subsidiary. Neither Seller nor any Seller Subsidiary is a party to, bound by or negotiating any collective bargaining agreement, nor are any of their respective employees represented by any labor union or similar organization. Seller and each Seller Subsidiary are in compliance with all applicable laws respecting employment and employment practices, terms and conditions of employment and wages and hours, other than any noncompliance that, individually or in the aggregate, would not have a material adverse effect on Seller, and neither Seller nor any Seller Subsidiary has engaged in any unfair labor practice that would have a material adverse effect on Seller.

(t) Employee Benefit Plans.

(i) Section 3.01(t)(i) of the Seller Disclosure Schedule contains a complete and accurate list of all bonus, incentive, deferred compensation, pension (including, without limitation, Seller Pension Plans, as defined below), retirement, profit-sharing, thrift, savings, employee stock ownership, stock bonus, stock purchase, restricted stock, stock option, severance, welfare (including, without limitation, “welfare plans” within the meaning of Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)), fringe benefit plans, employment, change in control, retention or severance agreements, consulting agreements or arrangements and all similar practices, policies and arrangements maintained or contributed to (currently or within the last six years) by (A) Seller or any Seller Subsidiary and in which any employee or former employee (the “Seller Employees”), consultant or former consultant (the “Seller Consultants”), officer or former officer (the “Seller Officers”), or director or former director (the “Seller Directors”) of Seller or any Seller Subsidiary participates or to which any such Seller Employees, Seller Consultants, Seller Officers or Seller Directors are parties or (B) any Seller ERISA Affiliate (as defined below) (collectively, the “Compensation and Benefit Plans”). Notwithstanding the foregoing, the term “Compensation and Benefit Plans” shall not include plans, funds, programs, policies, practices or procedures that are maintained or funded (A) by Seller Employees, Seller Consultants, Seller Officers or Seller Directors for their own benefit or for the benefit of their employees, such as individual retirement arrangements or plans described in Section 401(a) of the Code benefiting (or intended to benefit) themselves or persons who are not Seller Employees or (B) by persons or entities who are not Seller ERISA Affiliates (as defined below). Neither Seller nor any Seller Subsidiary has any commitment to create any additional Compensation and Benefit Plan or to modify or change any existing Compensation and Benefit Plan, except to the extent required by law and as otherwise contemplated by Section 6.02 of this Agreement.

(ii) Except in a manner that would not have a material adverse effect on Seller, each Compensation and Benefit Plan has been operated and administered in accordance with its terms and with applicable law, including, but not limited to, ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act of 1967 (the “Age Discrimination in Employment Act”), or any regulations or rules promulgated thereunder, and all filings, disclosures and notices required by ERISA, the Code, the Securities Act, the Exchange Act, the

A-16

Age Discrimination in Employment Act and any other applicable law have been timely made. Each Compensation and Benefit Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA (a “Seller Pension Plan”) and which is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter (including a determination that the related trust under such Compensation and Benefit Plan is exempt from tax under Section 501(a) of the Code) from the IRS, or is in the form of a prototype or volume submitter plan that is the subject of a favorable opinion letter from the IRS upon which Seller is entitled to rely, and Seller is not aware of any circumstances likely to result in revocation of any such favorable determination letter or opinion letter. There is no material pending or, to the actual knowledge of Seller, threatened legal action, suit or claim relating to the Compensation and Benefit Plans other than routine claims for benefits thereunder. Neither Seller nor any Seller Subsidiary has engaged in a transaction, or omitted to take any action, with respect to any Compensation and Benefit Plan that would reasonably be expected to subject Seller or any Seller Subsidiary to a tax or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming for purposes of Section 4975 of the Code that the taxable period of any such transaction expired as of the date hereof.

(iii) No liability (other than for payment of premiums to the Pension Benefit Guaranty Corporation (the “PBGC”) which have been made or will be made on a timely basis) under Title IV of ERISA has been or is expected to be incurred by Seller or any subsidiary of Seller with respect to any ongoing, frozen or terminated “single-employer plan,” within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or any single-employer plan of any entity (a “Seller ERISA Affiliate Plan”) which is considered one employer with Seller under Section 4001(a)(14) of ERISA or Section 414(b), (c) or (m) of the Code (a “Seller ERISA Affiliate”). During the six years prior to the Effective Time, none of Seller, any Seller Subsidiary nor any Seller ERISA Affiliate has contributed, or has been obligated to contribute, to a multiemployer plan under Subtitle E of Title IV of ERISA (as defined in ERISA Sections 3(37)(A) and 4001(a)(3)). No notice of a “reportable event”, within the meaning of Section 4043 of ERISA, for which the 30-day reporting requirement has not been waived, has been required to be filed for any Compensation and Benefit Plan or by any Seller ERISA Affiliate Plan within the 12-month period ending on the date hereof, and no such notice will be required to be filed as a result of the transactions contemplated by this Agreement. The PBGC has not instituted proceedings to terminate any Seller Pension Plan or Seller ERISA Affiliate Plan and, to Seller’s actual knowledge, no condition exists that presents a material risk that such proceedings will be instituted. There is no pending investigation or enforcement action by the PBGC, the Department of Labor (“DOL”), the IRS or any other Governmental Authority with respect to any Compensation and Benefit Plan and, to Seller’s actual knowledge, no such investigation or action is threatened or anticipated. Under each Seller Pension Plan and Seller ERISA Affiliate Plan, as of the date of the most recent actuarial valuation performed prior to the date of this Agreement, the actuarially determined present value of all “benefit liabilities”, within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in such actuarial valuation of such Seller Pension Plan or Seller ERISA Affiliate Plan), did not exceed the then current value of the assets of such Seller Pension Plan or Seller ERISA Affiliate Plan and since such date there has been neither an adverse change in the financial condition of such Seller Pension Plan or Seller ERISA Affiliate Plan nor any amendment or other change to such Seller Pension Plan or Seller ERISA Affiliate Plan that would increase the amount of benefits thereunder which reasonably could be expected to change such result and that, individually or in the aggregate, would have a material adverse effect on Seller.

(iv) All contributions required to be made under the terms of any Compensation and Benefit Plan or Seller ERISA Affiliate Plan or any employee benefit arrangements under any collective bargaining agreement to which Seller or any Seller Subsidiary is a party have been timely made or have been reflected on the Seller Financial Statements. Neither any Seller Pension Plan nor any

Each of Buyer and Buyer Sub has the right, power, authority and capacity to execute and deliver this Agreement and, subject to obtaining the Required Buyer Vote, the expiration of applicable regulatory waiting periods, and required filings under Federal and state securities laws, to perform its obligations under this Agreement. The Board of Directors of Buyer has the corporate power and authority to take the actions contemplated by Section 6.07 of this Agreement.

(f) SEC Filings; Sarbanes Oxley.

(i) Buyer and the Buyer Subsidiaries have filed all reports, registration statements, proxy statements and information statements required to be filed by Buyer or any of the Buyer Subsidiaries subsequent to December 31, 2010 under the Securities Act or under Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act with the SEC (together with all information incorporated therein by reference, the “Buyer SEC Documents”), except for any reports, registration statements, proxy statements or information statements the failure to file which would not have a material adverse effect on Buyer. All such filings, at the time of filing, complied in all material respects as to form and included all exhibits required to be filed under the applicable rules of the SEC. None of such documents, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(ii) The records, systems, controls, data and information of Buyer and the Buyer Subsidiaries are recorded, stored, maintained and operated under means (including any electronic, mechanical or

A-25

photographic process, whether computerized or not) that are under the exclusive ownership and direct control of Buyer or the Buyer Subsidiaries or accountants (including all means of access thereto and therefrom), except for any non-exclusive ownership and non-direct control that would not reasonably be expected to have a material adverse effect on Buyer. Buyer (x) has implemented and maintains disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) to ensure that material information relating to Buyer, including its consolidated Subsidiaries, is made known to the chief executive officer and the chief financial officer of Buyer by others within those entities, and (y) has disclosed, based on its most recent evaluation prior to the date hereof, to Buyer’s outside auditors and the audit committee of Buyer’s Board of Directors (i) any significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) which are reasonably likely to adversely affect Buyer’s ability to record, process, summarize and report financial information, and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Buyer’s internal controls over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act). These disclosures were made in writing by management to Buyer’s auditors and audit committee and a copy has previously been made available to Seller.

A-27

in the business, operations, assets or financial condition of Buyer and the Buyer Subsidiaries taken as a whole, and, to the actual knowledge of Buyer, no fact or condition exists which Buyer believes will cause such a material adverse change in the future.

(n) Loan Documentation. The Loan Documentation and Loan Assets included in the loan portfolio of the Buyer Subsidiaries is legally sufficient for the purposes intended thereby and creates enforceable rights of the Buyer Subsidiaries in accordance in all material respects with the terms of such Loan Documentation, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and other similar laws relating to or affecting the enforcement of creditors’ rights generally, by general equitable principles (regardless of whether enforceability is considered in a proceeding in equity or at law) and by an implied covenant of good faith and fair dealing, except for such insufficiencies as would not have a material adverse effect on Buyer. Except as set forth in Section 4.01(n) of the Buyer Disclosure Schedule, no debtor under any of the Loan Documentation has asserted as of the date hereof any claim or defense with respect to the subject matter thereof, which claim or defense, if determined adversely to Buyer, would have a material adverse effect on Buyer.

All such documents and

A-28

reports complied in all material respects with applicable requirements of law and rules and regulations in effect at the time such documents and reports were filed and contained in all material respects the information required to be stated therein, except for such documents and records the failure to comply with such laws, rules and regulations or contain such information would not reasonably be expected to have a material adverse effect on Buyer. None of such documents or reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, other than such reports and documents which the failure to file in such fashion would not reasonably be expected to have a material adverse effect on Buyer. There is no material unresolved violation, criticism or exception by any Governmental Authority or Regulatory Authority with respect to any report or letter relating to any examinations of Buyer or any of the Buyer Subsidiaries.

(q) Taxes. Except as set forth in Section 4.01(q) of the Buyer Disclosure Schedule, Buyer and the Buyer Subsidiaries have timely filed all material Tax Returns with respect to all material Taxes required to be filed with the appropriate tax authority through the date of this Agreement.

Buyer and the Buyer Subsidiaries have withheld or collected and paid over to the appropriate Governmental Authorities or are properly holding for such payment all Taxes required by law to be withheld or collected, except for such failures to withhold or collect as would not reasonably be expected to have a material adverse effect on Buyer. There are no liens for Taxes upon the assets of Buyer or any Buyer Subsidiary, other than liens for current Taxes not yet due and payable and liens that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Buyer.

A-29

similar arrangement with, or a commitment letter or similar submission to, or extraordinary supervisory letter from, any Regulatory Authorities that, individually or in the aggregate, could reasonably be expected to have a material adverse effect on Buyer. Neither Buyer nor any Buyer Subsidiary has been advised by any Regulatory Authority that such Regulatory Authority is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, judgment, decree, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission that, individually or in the aggregate, could reasonably be expected to have a material adverse effect on Buyer. Buyer and Buyer Bank are, and at the time of the Merger will be, “well capitalized” as such term is defined in Regulation Y.

(t) Employee Benefit Plans.

(i) Section 4.01(t)(i) of the Buyer Disclosure Schedule contains a complete and accurate list of all bonus, incentive, deferred compensation, pension (including, without limitation, Buyer Pension Plans, as defined below), retirement, profit-sharing, thrift, savings, employee stock ownership, stock bonus, stock purchase, restricted stock, stock option, severance, welfare (including, without limitation, “welfare plans” within the meaning of Section 3(1) of ERISA, fringe benefit plans, employment, change in control, retention or severance agreements, consulting agreements or arrangements and all similar practices, policies and arrangements maintained or contributed to (currently or within the last two years) by (A) Buyer or any Buyer Subsidiary and in which any employee or former employee (the “Buyer Employees”), consultant or former consultant (the “Buyer Consultants”), officer or former officer (the “Buyer Officers”), or director or former director (the “Buyer Directors”) of Buyer or any Buyer Subsidiary participates or to which any such Buyer Employees, Buyer Consultants, Buyer Officers or Buyer Directors are parties or (B) any Buyer ERISA Affiliate (as defined below) (collectively, the “Buyer Compensation and Benefit Plans”). Neither Buyer nor any Buyer Subsidiary has any commitment to create any additional Buyer Compensation and Benefit Plan or to modify or change any existing Buyer Compensation and Benefit Plan, except to the extent required by law and as otherwise contemplated by Sections 6.02 and 7.02 of this Agreement.

(ii) Except in a manner that would not reasonably be expected to have a material adverse effect on Buyer, each Buyer Compensation and Benefit Plan has been operated and administered in accordance with its terms and with applicable law, including, but not limited to, ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act, or any regulations or rules promulgated thereunder, and all filings, disclosures and notices required by ERISA, the Code, the Securities Act, the Exchange Act, the Age Discrimination in Employment Act and any other applicable law have been timely made. Each Buyer Compensation and Benefit Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA (a “Buyer Pension Plan”) and which is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter (including a determination that the related trust under such Buyer Compensation and Benefit Plan is exempt from tax under Section 501(a) of the Code) from the IRS and Buyer is not aware of any circumstances likely to result in revocation of any such favorable determination letter. There is no material pending or, to the actual knowledge of Buyer, threatened legal action, suit or claim relating to the Buyer Compensation and Benefit Plans other than routine claims for benefits thereunder. Neither Buyer nor any Buyer Subsidiary has engaged in a transaction, or omitted to take any action, with respect to any Buyer Compensation and Benefit Plan that would reasonably be expected to subject Buyer or any Buyer Subsidiary to a tax or penalty imposed by either Section 4975 of the Code or Section 502 of ERISA, assuming for purposes of Section 4975 of the Code that the taxable period of any such transaction expired as of the date hereof.

(iii) No liability (other than for payment of premiums to the PBGC which have been made or will be made on a timely basis) under Title IV of ERISA has been or is expected to be incurred by Buyer or any subsidiary of Buyer with respect to any ongoing, frozen or terminated “single-employer

A-30

plan,” within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or any single-employer plan of any entity (a “Buyer ERISA Affiliate Plan”) which is considered one employer with Buyer under Section 4001(a)(14) of ERISA or Section 414(b), (c) or (m) of the Code (a “Buyer ERISA Affiliate”). None of Buyer, any Buyer Subsidiary or any Buyer ERISA Affiliate has contributed, or has been obligated to contribute, to a multi-employer plan under Subtitle E of Title IV of ERISA (as defined in ERISA Sections 3(37)(A) and 4001(a)(3)) at any time since September 26, 1980. No notice of a “reportable event”, within the meaning of Section 4043 of ERISA, for which the 30-day reporting requirement has not been waived, has been required to be filed for any Buyer Compensation and Benefit Plan or by any Buyer ERISA Affiliate Plan within the 12-month period ending on the date hereof, and no such notice will be required to be filed as a result of the transactions contemplated by this Agreement. The PBGC has not instituted proceedings to terminate any Buyer Pension Plan or Buyer ERISA Affiliate Plan and, to Buyer’s actual knowledge, no condition exists that presents a material risk that such proceedings will be instituted. There is no pending investigation or enforcement action by the PBGC, the DOL, the IRS or any other Governmental Authority with respect to any Buyer Compensation and Benefit Plan. Except as disclosed in Section 4.01(s)(iii) of the Buyer Disclosure Schedule, under each Buyer Pension Plan and Buyer ERISA Affiliate Plan, as of the date of the most recent actuarial valuation performed prior to the date of this Agreement, the actuarially determined present value of all “benefit liabilities”, within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in such actuarial valuation of such Buyer Pension Plan or Buyer ERISA Affiliate Plan), did not exceed the then current value of the assets of such Buyer Pension Plan or Buyer ERISA Affiliate Plan and since such date there has been neither an adverse change in the financial condition of such Buyer Pension Plan or Buyer ERISA Affiliate Plan nor any amendment or other change to such Buyer Pension Plan or Buyer ERISA Affiliate Plan that would increase the amount of benefits thereunder which reasonably could be expected to change such result and that, individually or in the aggregate, would have a material adverse effect on Buyer.

(iv) All contributions required to be made under the terms of any Buyer Compensation and Benefit Plan or Buyer ERISA Affiliate Plan or any employee benefit arrangements under any collective bargaining agreement to which Buyer or any Buyer Subsidiary is a party have been timely made or have been reflected on the Buyer Financial Statements. Neither any Buyer Pension Plan nor any Buyer ERISA Affiliate Plan has an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA and all required payments to the PBGC with respect to each Buyer Pension Plan and each Buyer ERISA Affiliate Plan have been made on or before their due dates. None of Buyer, any Buyer Subsidiary nor any Buyer ERISA Affiliate (x) has provided, or would reasonably be expected to be required to provide, security to any Buyer Pension Plan or to any Buyer ERISA Affiliate Plan pursuant to Section 401(a)(29) of the Code, and (y) has taken any action, or omitted to take any action, that has resulted, or would reasonably be expected to result, in the imposition of a lien under Section 412(n) of the Code or pursuant to ERISA that, individually or in the aggregate, would have a material adverse effect on Buyer.

(v) Except as disclosed in Section 4.01(t)(v) of the Buyer Disclosure Schedule, neither Buyer nor any Buyer Subsidiary has any obligations to provide retiree health and life insurance or other retiree death benefits under any Buyer Compensation and Benefit Plan, other than benefits mandated by Section 4980B of the Code.

(vi) Buyer and the Buyer Subsidiaries do not maintain any foreign Buyer Compensation and Benefit Plans.

(vii) With respect to each Buyer Compensation and Benefit Plan, if applicable, Buyer has provided or made available to Seller, true and complete copies of the existing: (A) Buyer Compensation and Benefit Plan documents and amendments thereto; (B) trust instruments and insurance contracts;

A-31

(C) most recent actuarial report and financial statement; (D) most recent summary plan description; (E) forms filed with the PBGC within the past year (other than for premium payments); (F) most recent determination letter issued by the IRS; and (G) any Form 5310, Form 5310A, Form 5300 or Form 5330 filed within the past year with the IRS.

(viii) Except as disclosed on Section 4.01(t)(viii) of the Buyer Disclosure Schedule, the consummation of the transactions contemplated by this Agreement would not, directly or indirectly (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), reasonably be expected to (A) entitle any Buyer Employee, Buyer Consultant or Buyer Director to any payment (including severance pay or similar compensation) or any increase in compensation, (B) result in the vesting or acceleration of any benefits under any Buyer Compensation and Benefit Plan or (C) result in any material increase in benefits payable under any Buyer Compensation and Benefit Plan.

(ix) Except as disclosed on Section 4.01(t)(ix) of the Buyer Disclosure Schedule, neither Buyer nor any Buyer Subsidiary maintains any compensation plans, programs or arrangements, the payments under which would not reasonably be expected to be deductible as a result of the limitations under Section 162(m) of the Code and the regulations issued thereunder.

(x) Except as disclosed on Section 4.01(t)(x) of the Buyer Disclosure Schedule, as a result, directly or indirectly, of the transactions contemplated by this Agreement (including, without limitation, as a result of any termination of employment prior to or following the Effective Time), none of Buyer, Seller or the Surviving Corporation, or any of their respective Subsidiaries, will be obligated to make a payment that would be characterized as an “excess parachute payment” to an individual who is a “disqualified individual” (as such terms are defined in Section 280G of the Code) of Buyer on a consolidated basis, without regard to whether such payment is reasonable compensation for personal services performed or to be performed in the future.

(u) Compliance with Laws. Except with respect to Environmental Laws, Taxes, and Buyer Compensation and Benefit Plans, which are the subject of Sections 4.01(w), 4.01(q) and 4.01(t), respectively, each of Buyer and the Buyer Subsidiaries:

A-32

adverse effect on Buyer, or (B) threatening to revoke any license, franchise, permit or governmental authorization, which revocations, individually or in the aggregate, would have a material adverse effect on Buyer, which has not been resolved to the satisfaction of the Governmental Authority which sent such notification or communication. There is no event which has occurred that, to the actual knowledge of Buyer, would reasonably be expected to result in the revocation of any such license, franchise, permit or governmental authorization and which would have a material adverse effect on Buyer; and

(iv) Buyer and the Buyer Subsidiaries have been and are in compliance with (A) the applicable provisions of the Sarbanes-Oxley Act and the related rules and regulations promulgated thereunder and (B) the applicable listing and corporate governance rules and regulations of the Nasdaq, except where such non-compliance would not have a material adverse effect on Buyer.

(v) Contracts. Except for Buyer Contracts filed as exhibits to the Buyer Filed SEC Documents, there are no Buyer Contracts that are required to be filed as an exhibit to any Buyer Filed SEC Document under the Exchange Act and the rules and regulations promulgated thereunder. Neither Buyer nor any Buyer Subsidiary, nor, to the actual knowledge of Buyer, any other party thereto, is in default under any contract, agreement, commitment, arrangement or other instrument to which it is a party, by which its respective assets, business or operations may be bound or affected in any way, or under which it or its respective assets, business or operations receive benefits, and there has not occurred any event that, with the lapse of time or the giving of notice or both, would constitute a default except, in each case, for defaults that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on Buyer.

(cc) Adequate Shares; No Financing Required.

Buyer has the aggregate or readily available financing to fund the cash consideration to be paid in the Merger.

To Buyer’s actual knowledge, there are no applicable laws, conditions of record, or other impediments that materially interfere with the intended use by Buyer or the Buyer Subsidiaries of any of the material real properties owned or leased by Buyer or any Buyer Subsidiary and used in the business of Buyer and any Buyer Subsidiary.

Buyer and the Buyer Subsidiaries are insured with reputable insurers against such risks and in such amounts as the management of Buyer reasonably has determined to be prudent in accordance with industry practices. All such insurance policies are in full force and effect, Buyer and the Buyer Subsidiaries are not in material default thereunder and all claims thereunder have been filed in due and timely fashion, except with respect to such policies and claims, the failure to maintain or file would not reasonably be expected to have a material adverse effect on Buyer.

5.03. No Solicitation

of, or fail to enforce any confidentiality agreement or standstill agreement to which Seller is a party; (iv) enter into any agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal; or (v) take any action to render the provisions of any Takeover Laws inapplicable to any person (other than Buyer or the Buyer Subsidiaries) or group in connection with any Acquisition Proposal. Any violation of the foregoing restrictions by any of the Seller Representatives, whether or not such Seller Representative is so authorized and whether or not such Seller Representative is purporting to act on behalf of Seller or otherwise, shall be deemed to be a breach of this Agreement by Seller. Seller and Seller Sub shall, and shall cause each of the Seller Representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any persons with respect to any existing or potential Acquisition Proposal.

For purposes of this Agreement, “Acquisition Proposal” shall mean any inquiry, offer or proposal (other than an inquiry, offer or proposal from Buyer), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction.

(b) Notwithstanding the provisions of Section 5.03(a), Seller may take any of the actions described in clause (ii) of Section 5.03(a) if, but only if, (i) Seller has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of this Section 5.03; (ii) Seller’s Board of Directors (the “Seller Board”) determines in good faith, after consultation with and having considered the advice of its outside legal counsel and Seller’s Financial Advisor, that failure to take such actions would violate its fiduciary duties under applicable Pennsylvania law; (iii) Seller has provided Buyer with at least two (2) business days prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with respect to Seller or the Seller Subsidiaries or otherwise relating to an Acquisition Proposal, Seller receives from such person a confidentiality agreement with terms no less favorable to Seller than those contained in the confidentiality agreement between Seller and Buyer. Seller shall promptly provide to Buyer any non-public information regarding Seller or the Seller Subsidiaries provided to any other person which was not previously provided to Buyer, such additional information to be provided no later than the date of provision of such information to such other party.

(c) Seller shall promptly (and in any event within twenty-four (24) hours) notify Buyer in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, Seller or the Seller Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, such notice shall include copies of such materials (including e-mails or other electronic communications) unless (i) such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement, (ii) disclosure of such materials jeopardizes the attorney-client privilege or (iii) disclosure of such materials contravenes any law, rule, regulation, order,

A-39

judgment or decree). Seller shall keep Buyer informed, on a current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

(d) Neither the Seller Board nor any committee thereof shall (i) withdraw, withhold, qualify or modify, or propose to withdraw, withhold, qualify or modify, in a manner adverse to Buyer in connection with the transactions contemplated by this Agreement (including the Merger and the Bank Merger), the Seller Board Recommendation (as defined in Section 7.06(f)), or make any statement, filing or release, in connection with the Seller Meeting (as defined in Section 7.06(e)) or otherwise, inconsistent with the Seller Board Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the Seller Board Recommendation); (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iii) enter into (or cause Seller or the Seller Subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any Acquisition Transaction or (B) requiring Seller to abandon, terminate or fail to consummate the Merger, the Bank Merger or any other transaction contemplated by this Agreement.

(e) Nothing contained in this Agreement shall prevent Seller or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Acquisition Proposal; provided that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

(f) Notwithstanding the provisions of Section 5.03(d), prior to the date of the Seller Meeting (as defined in Section 7.06(e)), the Seller Board may approve or recommend to the shareholders of Seller a Superior Proposal (as defined below) and withdraw, qualify or modify the Seller Board Recommendation in connection therewith (a “Seller Subsequent Determination”) after the third business day following Buyer’s receipt of a notice (the “Notice of Superior Proposal”) from Seller advising Buyer that the Seller Board has decided that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of this Section 5.03) constitutes a Superior Proposal (it being understood that Seller shall be required to deliver a new Notice of Superior Proposal in respect of any revised Superior Proposal from such third party or its affiliates that Seller proposes to accept) if, but only if, (i) the Seller Board has reasonably determined in good faith, after consultation with and having considered the advice of outside legal counsel and Seller’s Financial Advisor, that failure to take such actions would violate its fiduciary duties under applicable Pennsylvania law, (ii) during the three (3) business day period after receipt of the Notice of Superior Proposal by Buyer, Seller and the Seller Board shall have cooperated and negotiated in good faith with Buyer and give due consideration to such adjustments, modifications or amendments to the terms and conditions of this Agreement as may be proposed by Buyer in making a determination whether Seller will proceed with the Seller Board Recommendation without a Seller Subsequent Determination; provided, however, that neither Buyer nor Seller shall have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement, and (iii) at the end of such three (3) business day period, after taking into account any such adjusted, modified or amended terms as may have been proposed by Buyer since its receipt of such Notice of Superior Proposal, the Seller Board has again in good faith made the determination (A) in clause (i) of this Section 5.03(f) and (B) that such Acquisition Proposal constitutes a Superior Proposal. Notwithstanding the foregoing, the changing, qualifying or modifying of the Seller Board Recommendation or the making of a Seller Subsequent Determination by the Seller Board shall not change the approval of the Seller Board for purposes of causing any Takeover Laws to be inapplicable to this Agreement and the Voting Agreements and the transactions contemplated hereby and thereby, including the Merger and the Bank Merger.

For purposes of this Agreement, “Superior Proposal” shall mean any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an Acquisition Transaction on terms that the Seller Board determines in its good faith judgment, after consultation with and having considered the advice of outside legal counsel and Seller’s Financial Advisor of nationally recognized reputation (i) would, if consummated, result in the acquisition of all, but not less than all, of the

A-40

issued and outstanding shares of Seller common stock or all, or substantially all, of the assets of Seller and the Seller Subsidiaries on a consolidated basis; (ii) would result in a transaction that (A) involves consideration to the holders of the Seller Shares that is more favorable, from a financial point of view, than the consideration to be paid to Seller’s shareholders pursuant to this Agreement, considering, among other things, the nature of the consideration being offered and any material regulatory approvals or other risks associated with the timing of the proposed transaction beyond or in addition to those specifically contemplated hereby, and which proposal is not conditioned upon obtaining additional financing and (B) is, in light of the other terms of such proposal, more favorable to Seller’s shareholders than the Merger and the transactions contemplated by this Agreement; and (iii) is reasonably likely to be completed on the terms proposed, in each case taking into account all legal, financial, regulatory and other aspects of the proposal.

5.04. Delivery of Information

Seller shall furnish to Buyer promptly after such documents are available: (a) all reports, proxy statements or other communications by Seller to its shareholders generally; and (b) all press releases relating to any transactions.

5.06. No Control

Nothing contained in this Agreement shall give Buyer, directly or indirectly, the right to control or direct the operations of Seller or the Seller Subsidiaries prior to the Effective Time. Prior to the Effective Time, each of Seller and Buyer shall exercise, consistent with the terms of this Agreement, complete control and supervision over its and its subsidiaries respective operations.

5.09. [Reserved]

5.10. Dividend Reinvestment

Seller shall take all such necessary action to suspend the acceptance of dividends and other contributions of participants in the Seller’s Dividend Reinvestment Plan (“DRIP”) effective promptly after the date of this Agreement (taking into account any Seller dividends that have been declared but not yet paid as of the date

A-41

hereof). In addition, prior to the Effective Time, Seller shall take such action as is necessary to terminate the DRIP and shall distribute all Seller Shares and the value of all cash held in participant’s plan accounts in accordance with the terms of the DRIP.

The accounts of all participants and beneficiaries in the ESOP as of the Effective Time shall become fully vested as of the Effective Time. Each Seller Share held in the ESOP shall be converted into the Merger Consideration The Merger Consideration received with respect to the unallocated Seller Shares held in the ESOP shall first be used to repay the then outstanding balance of the ESOP loan in its entirety, with the excess amount of the Merger Consideration received with respect to the unallocated Seller Shares to be allocated proportionately to all holders of ESOP accounts based on their account balances as of the beginning of the plan year in which the ESOP is terminated. As soon as practicable after the date hereof, Seller shall prepare and file or cause to be filed all necessary documents with the IRS for a determination letter with respect to the termination of the ESOP. Prior to the Effective Time, Seller and, following the Effective Time, Buyer shall use their reasonable best efforts to obtain such favorable determination letter as promptly as practicable (including, but not limited to, adopting such amendments to the ESOP as may be requested by the IRS as a condition to its issuance of a favorable determination letter). As soon as practicable following the later of the Effective Time or the receipt of a favorable determination letter from the IRS regarding the qualified status of the ESOP upon its termination, the account balances in the ESOP shall be either distributed to participants and beneficiaries or rolled over to an eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct.

(b) 401(k) Plan Matters. Seller and Seller Sub shall take all actions necessary to terminate the Seller’s Retirement Savings Plan (the “401(k) Plan”) effective immediately prior to the Effective Time. The accounts of all participants and beneficiaries in the 401(k) Plan as of such termination shall become fully vested upon termination of the 401(k) Plan. As soon as practicable following the Effective Time, the account balances in the 401(k) Plan shall be either distributed to participants and beneficiaries or rolled over to an eligible tax-qualified retirement plan or individual retirement account as a participant or beneficiary may direct.

Each Continuing Employee shall be credited with years of service with Seller or Seller Sub for purposes of eligibility, vesting, entitlements to benefits and levels of benefits (but not for benefit accrual purposes under any defined benefit plan or agreement) in the employee benefit plans of Buyer, and shall retain the vacation accrual earned under Seller’s vacation policy as of the Effective Time so that such Continuing Employee shall receive under Buyer’s vacation policy a vacation benefit no less than what such Continuing Employee had earned under Seller’s vacation policy as of the Effective Time; provided, however, that any future accrual of benefits shall be in accordance with Buyer’s vacation policy, subject to carryover limitations applicable to such future accruals.

For purposes of clarification, and not by way of limitation, all Continuing Employees shall commence participation in Buyer’s Employee Stock Ownership Plan (the “Employee Stock Ownership Plan”) as of the Effective Time, but such Continuing Employees shall not be eligible to participate in Buyer’s Defined Benefit Pension Plan (the “Defined Benefit Pension Plan”), participation in which has been frozen since July 31, 2007. The foregoing covenants shall survive the Merger, and Buyer shall, before the Effective Time, adopt resolutions that amend its tax-qualified retirement plans to the extent necessary to provide for the service credits applicable to Continuing Employees referenced herein.

(b) Concurrently with the execution of this Agreement, Buyer, Buyer Sub, Seller and Seller Sub shall enter into a Termination and Release Agreement and a Noncompetition Agreement with each of Charlotte A. Zuschlag, Charles P. Evanoski, Frank D. Martz and Todd F. Palkovich, and Buyer and Buyer Sub agree to honor the terms of such agreements. As of the Effective Time of the Merger, Seller Sub shall make lump sum cash payments to each other Seller Officer who has a change in control agreement in effect as of the date hereof, and the Surviving Bank Corporation shall provide continued insurance coverage to each of such officers in accordance with the terms of the change in control agreements, in each case

A-43

regardless of whether such officers are subsequently retained as employees of Buyer or Buyer Sub following the Effective Time. Section 6.02(b) of the Seller Disclosure Schedule sets forth the estimated lump sum cash payments to be made to such other Seller Officers based upon the assumptions set forth in such schedule. Concurrently with the execution of this Agreement, Buyer and Buyer Sub shall enter into employment agreements with Ms. Zuschlag, Mr. Evanoski, Mr. Martz and Mr. Palkovich and a Consulting Agreement with Mr. Evanoski to commence consulting immediately after the expiration of Mr. Evanoski’s employment agreement.

(c) Buyer and Buyer Sub agree to honor the terms of Seller’s Amended and Restated Excess Benefit Plan, the Amended and Restated Supplemental Executive Retirement Plan of Seller and Seller Sub, each as amended effective October 29, 2014, and the Amended and Restated Director Retirement Agreements that Seller and Seller Sub have with their directors and to make payments in accordance with the current terms of such plans and agreements and any applicable payment elections made thereunder.

(d) As of the Effective Time, Buyer shall succeed Seller as sponsor and administrator of the Compensation and Benefit Plans and shall take such action as necessary to effectuate such changes. Subject to Sections 6.02(a) and 6.02(c), Buyer may terminate, merge or amend any Compensation and Benefit Plan or may cease contributions to any Compensation and Benefit Plan to the extent permitted by applicable law; provided, however, that Buyer will provide any benefits to which Seller Employees or their respective spouses, former spouses or other qualifying beneficiaries may be entitled by reason of qualifying events occurring prior to, on or after the Effective Time by virtue of any provisions of any employee welfare benefit plan or group insurance contract or any laws, statutes or regulations requiring any continuation of benefit coverage upon the happening of certain events, such as the termination of employment or change in beneficiary or dependent status, including, without limitation, such requirements under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, from and after the Effective Time through the remaining legally-required period of coverage.

(e) Buyer shall provide a retention pool in the aggregate amount set forth in Section 6.02(e) of the Seller Disclosure Schedule (the “Retention Pool”) for the purposes of retaining the services of employees of the Seller and the Seller Subsidiaries (“Retention Employees”) who are key employees. The Chief Executive Officer of the Seller shall determine, subject to approval by the President and Chief Executive Officer of the Buyer, the Retention Employees eligible to receive retention awards from the Retention Pool (each, a “Retention Bonus”) and any criteria for payment of the Retention Bonus, and shall determine the final allocation of payments from the Retention Pool. Any Retention Bonus shall be intended to retain the services of the recipient through, and shall be payable (if such recipient still remains employed by the Seller and the Seller Subsidiaries or Buyer and the Buyer Subsidiaries, as the case may be, at such time) at, the end of the month following the conversion of the data processing system of Seller.

6.03. Exchange Listing

Buyer shall file a listing application with the Nasdaq for the Buyer Shares to be issued to the former holders of Seller Shares in the Merger at the time prescribed by applicable rules and regulations of the Nasdaq, and shall use all commercially reasonable efforts to cause the Buyer Shares to be issued in connection with the Merger to be approved for listing on the Nasdaq, subject to official notice of issuance, prior to the Closing Date. In addition, Buyer will use its best efforts to maintain its listing on the Nasdaq.

6.04. Notification

Between the date of this Agreement and the Closing Date, Buyer shall promptly notify Seller in writing if Buyer becomes aware of any fact or condition that (i) causes or constitutes a breach in any material respect of any of Buyer’s or Buyer Sub’s representations and warranties or (ii) would (except as expressly contemplated by this Agreement) cause or constitute a breach in any material respect of any such representation or warranty had such representation or warranty been made as of the time of occurrence or discovery of such fact or condition.

A-44

Should any such fact or condition require any change in the Buyer Disclosure Schedule, Buyer shall promptly deliver to Seller a supplement to the Buyer Disclosure Schedule specifying such change (“Updated Buyer Disclosure Schedule”); provided, however, that the disclosure of such change in the Updated Buyer Disclosure Schedule shall not be deemed to constitute a cure of any breach of any representation or warranty made pursuant to this Agreement unless consented to in writing by Seller. During the same period, Buyer shall promptly notify Seller of (i) the occurrence of any breach in any material respect of any of Buyer’s or Buyer Sub’s covenants contained in this Agreement, (ii) the occurrence of any event that may make the satisfaction of the conditions in this Agreement impossible or unlikely in any material respect or (iii) the occurrence of any event that is reasonably likely, individually or taken with all other facts, events or circumstances known to Buyer, to result in a material adverse effect with respect to Buyer.

6.05. Takeover Laws

Buyer shall take all necessary steps to (a) exempt (or cause the continued exemption of) this Agreement, the Merger and the Bank Merger from the requirements of any Takeover Law and from any provisions under its Articles of Incorporation and Bylaws, as applicable, by action of the Board of Directors of Buyer or otherwise, and (b) assist in any challenge by Seller to the validity, or applicability to the Merger or the Bank Merger, of any Takeover Law.

6.06. Officers’ and Directors’ Indemnification and Insurance

(a) From and after the Effective Time, each of Buyer and the Surviving Corporation shall indemnify and hold harmless each present and former director and officer of Seller and its Subsidiaries (in each case, when acting in such capacity) (each an “Indemnified Party”) against any costs or expenses (including reasonable attorney’s fees ), judgments, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of the fact that such person is or was as director or officer of Seller or any of its Subsidiaries and pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement to same extent as such persons are indemnified as of the date of this Agreement by Seller pursuant to applicable law as effect on the date of this Agreement, the Seller’s Articles of Incorporation and Bylaws or the governing or organizational documents of any Subsidiary of Seller; and Buyer and the Surviving Corporation shall also advance expenses as incurred by such Indemnified Party to the same extent as such persons are entitled to advancement of expenses as of the date of this Agreement by Seller pursuant to the Seller’s Articles of Incorporation and Bylaws or the governing or organizational documents of any Subsidiary of Seller; provided, that the Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification under applicable law as effect on the date of this Agreement or the Seller’s Articles of Incorporation and Bylaws.

(b) For a period of six (6) years after the Effective Time the Surviving Corporation shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by Seller (provided, that the Surviving Corporation may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the insured) with respect to claims arising from facts or events which occurred at or before the Effective Time; provided, however that the Surviving Corporation shall not be obligated to expend an amount in excess of $250,000 (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Corporation shall cause to be maintained policies of insurance which, in the Surviving Corporation’s good faith determination, provide the maximum coverage available at an amount equal to the Premium Cap. In lieu of the foregoing, Seller, in consultation with, but only upon the consent of Buyer, may obtain at or prior to the Effective Time a six-year “tail” policy under Seller’s existing directors’ and officers’ insurance policy

A-45

providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that does not exceed the Premium Cap.

(c) If Buyer, the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger, (ii) transfers or conveys all or substantially all its properties and assets to any person or (iii) transfers, by means of a distribution, sale, assignment or other transaction, all of the stock of the Surviving Corporation or all or substantially all of its assets, to any person, then, and in each such case, Buyer shall cause proper provision to be made so that the successor and assign of Buyer or the Surviving Corporation assumes the obligations set forth in this Section and in such event all references to the Surviving Corporation in this Section shall be deemed a reference to such successor and assign.

(d) Any Indemnified Party wishing to claim indemnification under Section 6.06(a), upon learning of any claim, action, suit, proceeding or investigation described above, shall promptly notify Buyer thereof; provided that the failure so to notify shall not affect the obligations of Buyer under Section 6.06(a) unless and only to the extent that Buyer is actually and materially prejudiced as a result of such failure.

(e) The provisions of this Section 6.06 shall survive consummation of the Merger and are intended to be for the benefit of, and to grant third party rights to, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives.

6.07. Appointment of Seller Directors to Board of Directors

Buyer shall appoint two of the current directors of Seller or Seller Sub (the “Seller Appointees”) to the Board of Directors of Buyer, which appointments shall be effective as of the Effective Time. The Seller Appointees shall serve until the next annual meeting of the shareholders of Buyer, and Buyer shall include the Seller Appointees on the list of nominees for which Buyer’s Board of Directors shall solicit proxies at such meeting and subsequent meetings until the Seller Appointees have served a full three-year term, unless such person earlier resigns or is removed for cause in accordance with Buyer’s Articles of Incorporation and Bylaws. One of the Seller Appointees shall be Charlotte A. Zuschlag and the other shall be selected by Seller and be reasonably acceptable to Buyer prior to the Effective Time.

6.08. Operation of Business

Buyer’s business, and the business of each of the Buyer Subsidiaries, will be conducted only in the ordinary and usual course consistent with past practice. Without the written consent of Seller, Buyer shall not, and shall cause each of the Buyer Subsidiaries not to, take any action which would have, individually or in the aggregate, a material adverse effect on Buyer or on the Surviving Corporation except, in each case, as may be required by applicable law or regulation. In addition, Buyer shall use reasonable efforts to cause the Merger to qualify as a reorganization with the meaning of Section 368(a) of the Code.

6.09. Buyer Forbearances

From the date hereof until the Effective Time, except as set forth in the Buyer Disclosure Schedule or as expressly contemplated by this Agreement, without the prior written consent of Seller, Buyer will not, and will cause the Buyer Subsidiaries not to, knowingly take any action that would, or would be reasonably likely to, (i) prevent or impede the Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code; or (ii) knowingly take any action that is intended or is reasonably likely to result in (x) any of its representations and warranties set forth in this Agreement being or becoming untrue in any material respect at any time prior to the Effective Time, (y) any of the conditions to the Merger set forth in Article Eight not being satisfied, or (z) a material violation of any provision of this Agreement, except, in each case, as may be required by applicable law.

(b) By either Seller or Buyer, if its respective Board of Directors so determines, upon written notification to the non-terminating party by the terminating party:

(i) if prior to the Closing Date, any representation and warranty of Seller or Seller Sub shall have become untrue such that the condition set forth at Section 8.01(a) would not be satisfied and which breach has not been cured within 30 calendar days following receipt by Seller of written notice of breach or is incapable of being cured during such time period;

(ii) if Seller or Seller Sub shall have failed to comply in any material respect with any covenant or agreement on the part of Seller or Seller Sub contained in this Agreement required to be

A-54

complied with prior to the date of such termination, which failure to comply shall not have been cured within 30 calendar days following receipt by Seller of written notice of such failure to comply or is incapable of being cured during such time period; or

(iii) if (i) the Seller Board (A) modifies, qualifies, withholds or withdraws the Seller Board Recommendation in a manner adverse to Buyer in connection with the transactions contemplated by this Agreement (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the Seller Board Recommendation), or makes any statement, filing or release, in connection with the Seller Meeting or otherwise, inconsistent with the Seller Board Recommendation, (B) breaches its obligations to call, give notice of and commence the Seller Meeting under Section 7.06(e), (C) approves or recommends an Acquisition Proposal, (D) fails to publicly recommend against a publicly announced Acquisition Proposal within ten (10) business days of being requested to do so by Buyer, (E) fails to publicly reconfirm the Seller Board Recommendation within ten (10) business days of being requested to do so by Buyer, or (F) resolves or otherwise determines to take, or announces an intention to take, any of the foregoing actions or (ii) there shall have been a material breach by Seller of Section 5.03.

(1) the Average Closing Price (as defined below) shall be less than the product of 0.85 and the Starting Price (as defined below); and

(2) (a) the number obtained by dividing the Average Closing Price by the Starting Price (such number being referred to herein as the “Buyer Ratio”) shall be less than (b) the number obtained by dividing the Index Price (as defined below) on the Walkaway Determination Date (as defined below) by the Index Price on the Starting Date (as defined below) (the “Index Ratio”) and subtracting 0.15 from such quotient;

subject to the following. If Seller elects to exercise its termination right pursuant to the immediately preceding sentence, it shall give prompt written notice to Buyer; provided that such notice of election to terminate may be withdrawn by Seller at any time within the aforementioned five-day period. During the five-day period commencing with its receipt of such notice, Buyer shall have the option of paying additional Merger Consideration by increasing the Exchange Ratio to equal the number obtained by dividing $15.89 by the greater of (i) the product of 0.85 and the Starting Price or (ii) the product obtained by multiplying the Index Ratio by the Starting Price (the “Buyer Top-up Notice”). If Buyer makes this election, within such five-day period, it shall give prompt written notice to Seller of such election and the revised Exchange Ratio, whereupon no termination shall have occurred pursuant to this Section 11.01(d)(iv) and this Agreement shall

A-55

remain in effect in accordance with its terms (except as the Exchange Ratio shall have been so modified), and any references in this Agreement to “Exchange Ratio” shall thereafter be deemed to refer to the Exchange Ratio after giving effect to any adjustment made pursuant to this Section 11.01(d)(iv). For purposes of this Section 11.01(d)(iv), the following terms shall have the following meanings:

“Average Closing Price” means the average of the last reported sale price per share of the Buyer Shares as reported on the Nasdaq (as reported in The Wall Street Journal or, if not reported therein, in another mutually agreed upon authoritative source) for each of the 10 consecutive trading days ending on the Walkaway Determination Date.

“Walkaway Determination Date” means the later of (i) the first date on which all necessary bank regulatory approvals or non-objections have been received (disregarding any waiting period), which list of such approvals and non-objections shall be mutually agreed upon in writing by Buyer and Seller within 30 days of the date of this Agreement or (ii) the date on which the Seller’s shareholders approve this Agreement.

“Index Price” on a given date means the closing value of the Nasdaq Bank Index as reported on Bloomberg.com, or if not reported therein, in another mutually agreed upon authoritative source.

“Per Share Consideration” shall mean the Exchange Ratio multiplied by the Average Closing Price.

“Starting Price” shall mean the average of the last reported sale price per share of Buyer Common Stock as reported on the Nasdaq (as reported in The Wall Street Journal or, if not reported therein, in another mutually agreed upon authoritative source) for each of the 10 consecutive trading days ending on the Starting Date.

“Starting Date” shall mean the last full trading day prior to the announcement by press release of the Merger or, if such announcement occurs after the close of trading on any trading day, such trading day.

If Buyer declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, non-acquisitive exchange of shares or similar transaction between the Starting Date and the Walkaway Determination Date (or establishes a record date in respect thereof), the prices for the common stock of Buyer shall be appropriately adjusted for the purposes of applying this Section 11.01(d)(iv).

11.02 Effect of Termination.

(a) If this Agreement is validly terminated by either Seller or Buyer pursuant to Section 11.01, this Agreement will forthwith become null and void and there will be no liability or obligation on the part of Seller, Seller Sub, Buyer or Buyer Sub, except (i) that the provisions of Sections 7.01, 12.06, 12.07, 12.11 and this Article Eleven will continue to apply following any such termination, (ii) that nothing contained herein shall relieve any party hereto from liability for any liabilities or damages arising out of its fraud or knowing breach of any provision of this Agreement and (iii) as provided in paragraphs (b)-(f) below.

(b) Seller shall promptly pay to Buyer a termination fee of $11,354,000 (the “Termination Fee”) if this Agreement is terminated by (i) Buyer pursuant to Section 11.01(c)(iii) or (ii) Seller pursuant to Section 11.01(d)(iii).

(c) In the event that this Agreement is terminated by Buyer or Seller pursuant to Section 11.01(b)(i) without the Required Seller Vote having been obtained, or Section 11.01(b)(ii), and (i) an Acquisition Proposal with respect to Seller shall have been publicly announced, disclosed or otherwise communicated to the Seller Board prior to the date specified in Section 11.01(b)(i) or prior to the Seller

A-56

Meeting, and (ii) within twelve (12) months of such termination, Seller shall have entered into a definitive agreement with respect to, or Seller shall have consummated, an Acquisition Transaction, then Seller shall pay to Buyer an amount equal to the Termination Fee.

(d) In the event that this Agreement is terminated by Buyer pursuant to Sections 11.01(c)(i) or (ii) and (A) an Acquisition Proposal with respect to Seller shall have been publicly announced, disclosed or otherwise communicated to the Seller Board prior to any breach by Seller of any representation, warranty, covenant or other agreement giving rise to such termination by Buyer or during the cure period therefor provided in Sections 11.01(c)(i) or (ii) and (B) within twelve (12) months of such termination, Seller shall have entered into a definitive agreement with respect to, or Seller shall have consummated, an Acquisition Transaction, then Seller shall pay to Buyer an amount equal to the Termination Fee.

(e) Any payment of the Termination Fee required to be made pursuant to this Section 11.02 shall be made not more than two (2) business days after the date of the event giving rise to the obligation to make such payment, unless the Termination Fee is payable as a result of the termination of this Agreement by Seller pursuant to Section 11.01(d)(iii), in which case, the Termination Fee shall be payable concurrently with such termination. All payments under this Section 11.02 shall be made by wire transfer of immediately available funds to an account designated by Buyer. No payment of the Termination Fee under this Section 11.02 shall limit in any respect any rights or remedies available to Buyer relating to any breach or failure of Seller to perform any representation, warranty, covenant or agreement set forth in this Agreement resulting, directly or indirectly, in the right to receive the Termination Fee under this Section 11.02.

(f) Buyer and Seller acknowledge that the agreements contained in this Section 11.02 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, Buyer would not enter into this Agreement. The Termination Fee amounts payable by Seller pursuant to this Section 11.02 constitute liquidated damages and not a penalty and shall be the sole monetary remedy of Buyer except in circumstances where no Termination Fee is payable. Accordingly, if Seller fails promptly to pay any amount due pursuant to this Section 11.02 and, in order to obtain such payment, Buyer commences a suit which results in a judgment against Seller for the amount set forth in this Section 11.02, Seller shall pay to Buyer its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the Termination Fee at a rate per annum equal to three-month LIBOR (as reported in The Wall Street Journal (Northeast edition), or if not reported therein, in another authoritative source selected by the party to which the payment is due) plus 200 basis points as in effect on the date such payment was required to be made.

ANNEX B

[Letterhead of FBR Capital Markets & Co.]

October 29, 2014

WesBanco, Inc.

One Bank Plaza

Wheeling, West Virginia 26003

Attn: Board of Directors

Members of the Board of Directors:

We understand that WesBanco, Inc. (“WSBC”) intends to enter into an Agreement and Plan of Merger (the “Agreement”) by and between WSBC, WesBanco Bank, Inc., a wholly owned subsidiary of WSBC (“WSB Bank”), ESB Financial Corporation (“ESBF”) and ESB Bank, a wholly owned subsidiary of ESBF (“ESB Bank”), pursuant to which, among other things (i) ESBF will merge with and into WSBC (the “Merger”) and (ii) each outstanding share of common stock, par value $0.01 per share (“ESBF Common Stock”), of ESBF will be converted into the right to receive 0.502 of a share of common stock, par value $2.0833 per share (“WSBC Common Stock”), of WSBC (the “Stock Consideration”) and $1.76 in cash (the “Cash Consideration” and, together with the Stock Consideration, the “Consideration”). We also understand that pursuant to the Agreement, immediately following the Merger, (i) ESB Bank will merge (the “Bank Merger” and, together with the Merger, the “Transaction”) with and into WSB Bank and (ii) each share of capital stock of ESB Bank will be canceled without consideration payable therefor.

You have requested that FBR Capital Markets & Co. (“FBRC”) render an opinion (this “Opinion”) to the Board of Directors of WSBC (the “Board”) with respect to the fairness, from a financial point of view, to WSBC of the Consideration to be issued and paid by WSBC in respect of the outstanding shares of ESBF Common Stock in the Merger pursuant to the Agreement.

In arriving at our Opinion, we have made such reviews, analyses and inquiries as we have deemed necessary and appropriate under the circumstances. Among other things, we have:

(i) reviewed an execution version of the Agreement;

(ii) reviewed certain publicly available business and financial information relating to ESBF and WSBC;

(iii) reviewed certain other business, financial and operating information relating to ESBF, including financial forecasts for ESBF for the fiscal years ending December 31, 2014 through December 31, 2016 prepared and provided to us by management of ESBF (the “ESBF Projections”), as adjusted and extended by the management of WSBC through the fiscal year ending December 31, 2019, to take into account certain cost savings and synergies expected by the management of WSBC to result from the Transaction and WSBC’s ownership, control and operation of ESBF and ESB Bank following the consummation of the Transaction (the “WSBC Projections for ESBF”);

(iv) reviewed certain other business, financial and operating information relating to WSBC, including financial forecasts for WSBC for the fiscal years ending December 31, 2016 through December 31, 2019 prepared and provided to us by management of WSBC (the “WSBC Projections”);

(v) met with certain members of the managements of ESBF and WSBC to discuss the business and prospects of ESBF and WSBC and the proposed Transaction;

(vi) reviewed certain financial data for ESBF and WSBC and compared that data with similar data for companies with publicly traded equity securities that we deemed relevant;

B-1

(vii) reviewed certain financial terms of the proposed Merger and compared certain of those terms with the publicly available financial terms of certain business combinations and other transactions that we deemed relevant; and

(viii) considered such other information, financial studies, analyses and investigations and financial, economic and market criteria that we deemed relevant.

As you are aware, we have relied upon and assumed, without independent verification, the accuracy and completeness of all data, material and other information furnished, or otherwise made available, to us, discussed with or reviewed by us, or publicly available, and do not assume any responsibility with respect to such data, material and other information. With respect to the ESBF Projections, management of ESBF has advised us, and we have assumed, that the ESBF Projections have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of the management of ESBF with respect to the future financial performance of ESBF. With respect to the WSBC Projections for ESBF, management of WSBC has advised us, and we have assumed, that the WSBC Projections for ESBF have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of the management of WSBC with respect to the future financial performance of ESBF following the consummation of the Transaction, after giving effect to the cost savings and synergies expected by WSBC management to result from the Transaction and WSBC’s ownership, control and operation of ESBF and ESB Bank after giving effect to the Transaction. With respect to the WSBC Projections, management of WSBC has advised us, and we have assumed, that the WSBC Projections have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of the management of WSBC with respect to the future financial performance of WSBC. We have relied without independent verification upon the assessment of the management of WSBC with respect to the timing and risks associated with the integration of the businesses of WSBC and ESBF and the risks associated with WSBC’s and ESBF’s current and contemplated products, services and business models. We express no view or opinion with respect to the ESBF Projections, the WSBC Projections for ESBF, the WSBC Projections or the assumptions on which they are based including, without limitation, the cost savings and synergies expected by WSBC management to result from the Transaction, which cost savings and synergies we have, at your direction, assumed will be achieved in the amounts and at the times indicated thereby. You have advised us and we have assumed without undertaking any responsibility for the independent verification thereof, that the WSBC Projections for ESBF, the WSBC Projections and the assumptions on which they are based are a reasonable basis on which to evaluate ESBF, WSBC and the proposed Transaction and, at your direction, we have used and relied upon the WSBC Projections for ESBF and the WSBC Projections for purposes of our analyses and this Opinion. We have also relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of ESBF or WSBC since the dates of the most recent financial statements and other information, financial or otherwise, provided to us that would be material to our analyses or this Opinion, and that there is no information or any facts or developments that would make any of the information reviewed by us incomplete or misleading. We also have assumed, with your consent, that (i) in the course of obtaining any regulatory or third party consents, approvals or agreements in connection with the Transaction, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on ESBF, WSBC or the contemplated benefits of the Transaction; (ii) the representations and warranties made by the parties in the Agreement are accurate and complete in all respects material to our analyses and this Opinion; (iii) each party to the Agreement will perform all of its covenants and obligations thereunder; (iv) the Transaction will be consummated in accordance with the terms of the Agreement, without waiver, modification or amendment of any term, condition or provision thereof that is material to our analyses or this Opinion; and (v) that the Transaction will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. We have also assumed that the Agreement, when executed by the parties thereto, will conform to the execution version reviewed by us in all respects material to our analyses.

This Opinion only addresses the fairness, from a financial point of view, to WSBC of the Consideration to be issued and paid by WSBC in respect of the outstanding shares of ESBF Common Stock in the Merger pursuant to the Agreement and does not address any other aspect or implication of the Transaction or any agreement,

B-2

arrangement or understanding entered into in connection therewith or otherwise, including, without limitation, the form or, except to the extent expressly provided herein, the amounts of the Consideration to be issued and paid in the Merger; the allocation of the outstanding shares of WSBC Common Stock after giving effect to the Transaction as between the current holders of WSBC Common Stock and the current holders of ESBF Common Stock or any individual members or groups thereof; the dilutive or other effects of the Transaction on the existing holders of WSBC Common Stock; the solvency or fair value of WSBC, ESBF or any other entity or person or their respective assets or liabilities under any laws relating to bankruptcy, insolvency, fraudulent conveyance or similar matters; any tax implications of the Transaction to WSBC or its security holders or any other party; the fairness of any portion or aspect of the Transaction to the current holders of any class of securities, creditors or other constituencies of WSBC, ESBF or to any other party; or the fairness of the amount or nature of, or any other aspect relating to, any compensation or consideration to be received by or otherwise payable to any officers, directors, employees, securityholders or affiliates of any party to the Transaction, or class of such persons, relative to the Consideration or otherwise. The issuance of this Opinion was approved by an authorized internal committee of FBRC.

We are not expressing any opinion or providing any advice, counsel or interpretation, with respect to matters that require legal, regulatory, accounting, insurance, tax or other similar professional advice. We have assumed that any such opinions, advice, counsel or interpretations have been or will be obtained by WSBC from appropriate professional sources. Furthermore, we have, with your consent, relied upon the assessments by WSBC and its other advisors as to all legal, regulatory, accounting, insurance and tax matters with respect to WSBC, ESBF and the Transaction.

This Opinion is necessarily based upon information made available to us as of the date hereof and financial, economic, market and other conditions as they exist and can be evaluated on the date hereof. Although subsequent developments may affect this opinion, we do not have any obligation to update, revise or reaffirm this opinion. As you are aware, the credit, financial and stock markets have experienced significant volatility and we express no opinion or view as to any potential effects of such volatility on WSBC, WSB Bank, ESBF, ESB Bank or the Transaction. This Opinion does not address the relative merits of the Transaction as compared to alternative transactions or strategies that might be available to WSBC, WSB Bank, ESBF, ESB Bank or any other party to the Transaction, nor does it address the underlying business decision of the Board, WSBC, WSB Bank, ESBF, ESB Bank or any other party to proceed with the Transaction. Furthermore, in connection with this Opinion, we have not been requested to make, and have not made, any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (contingent or otherwise) of WSBC, WSB Bank, ESBF, ESB Bank or any other party, nor were we provided with any such appraisal or evaluation. In addition, we have not received or reviewed any individual credit files nor have we made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of WSBC, WSB Bank, ESBF, ESB Bank or any of their respective subsidiaries and we have not been furnished with any such evaluations or appraisals. We are not experts in the evaluation of loan, lease, investment or trading portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto and, accordingly, we have assumed that such allowances for losses are adequate to cover such losses. We do not express any opinion as to what the value of shares of WSBC Common Stock actually will be when issued pursuant to the Merger, or the price or range of prices at which WSBC Common Stock or ESBF Common Stock may be purchased or sold at any time. With your consent, we have assumed that the shares of WSBC Common Stock to be issued in the Merger will be listed on the NASDAQ Global Select Market.

We have acted as financial advisor to WSBC in connection with the Transaction and will receive fees for our services, which is contingent upon the successful completion of the Merger. We will also receive a fee for rendering this Opinion, which is not contingent upon the successful completion of the Merger. In addition, WSBC has also agreed to indemnify us and certain related parties for certain liabilities arising out of or related to our engagement and to reimburse us for certain expenses incurred in connection with our engagement.

In the ordinary course of business, we and our affiliates may acquire, hold or sell, for our and our affiliates own accounts and the accounts of customers, equity, debt and other securities and financial instruments (including bank loans and other obligations) of WSBC, ESBF, certain of their affiliates and any other company that may be involved in the Transaction. We and our affiliates may in the future provide investment banking and other financial services to WSBC, ESBF and certain of their respective affiliates, for which we and our affiliates would expect to receive compensation. FBRC has adopted policies and procedures designed to preserve the independence of its research and credit analysts whose views may differ from those of the members of the team of investment banking professionals that are advising WSBC.

It is understood that this Opinion is for the information of the Board (in its capacity as such) in connection with its consideration of the proposed Merger. This Opinion is not intended to and should not be construed as creating any fiduciary duty on the part of FBRC to the Board, WSBC, WSB Bank any security holder of WSBC or any other party. This Opinion does not constitute a recommendation to the Board, WSBC, WSB Bank any securityholder of WSBC or any other person as to how to act or vote on any matter relating to the Transaction or otherwise.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration to be issued and paid by WSBC in respect of the outstanding shares of ESBF Common Stock in the Merger pursuant to the Agreement is fair, from a financial point of view, to WSBC.

Very truly yours,

The Board of Directors

ESB Financial Corporation

600 Lawrence Avenue

Ellwood City, PA 16117

Members of the Board:

You have requested our opinion as investment bankers (the “Opinion”) as to the fairness, from a financial point of view, to the shareholders of ESB Financial Corporation (“ESB”) with regard to the Agreement and Plan of Merger dated as of October 29, 2014 (the “Agreement”) by and among WesBanco, Inc. (“WesBanco”), its wholly owned subsidiary WesBanco Bank, Inc., and ESB and ESB’s wholly owned subsidiary, ESB Bank, with WesBanco being the surviving corporation in the proposed merger of ESB with and into WesBanco (the “Merger”). Pursuant to the terms of the Agreement, each share of ESB common stock, par value $0.01 per share issued and outstanding immediately prior to the Effective Time of the merger (as defined in the Agreement) shall, by virtue of the Agreement and without any action on the part of the holder thereof, be converted into and exchangeable for the right to receive, subject to the provisions set forth in the Agreement, (i) 0.502 (the “Exchange Ratio”) of a share of WesBanco and (ii) $1.76 in cash, without interest. The 0.502 of a share of WesBanco to be issued, together with the $1.76 of cash to be paid in exchange for share of ESB, pursuant to Section 2.01 of the Agreement is referred to herein as the “Merger Consideration”.

Mufson Howe Hunter & Company LLC (“Mufson Howe Hunter” or “we”) has acted as financial advisor to ESB. In connection with our opinion, we have, among other things:

i. reviewed and analyzed a draft copy of the Agreement;

ii. reviewed and analyzed the audited consolidated financial statements of ESB for the three fiscal years ended December 31, 2013, the unaudited consolidated financial statements of ESB for the six months ended June 30, 2014 and ESB’s earnings release for the third quarter ended September 30, 2014;

iii. reviewed and analyzed the audited consolidated financial statements of WesBanco for the three fiscal years ended December 31, 2013, the unaudited consolidated financial statements of WesBanco for the six months ended June 30, 2014 and WesBanco’s earnings release for the third quarter ended September 30, 2014;

iv. reviewed and analyzed certain other publicly available information concerning ESB and WesBanco;

v. held discussions with ESB and WesBanco’s senior management and advisors, including, without limitation, discussions regarding estimates of certain cost savings, operating synergies, merger charges and the pro forma financial impact of the Merger on WesBanco;

vi. reviewed certain non-publicly available information concerning ESB, including without limitation, internal financial analyses and forecasts prepared by its management, and held discussions with ESB’s senior management regarding recent developments and regulatory matters;

vii. reviewed certain non-publicly available information concerning WesBanco, including without limitation, internal financial analyses and forecasts prepared by its management, and held discussions with WesBanco’s senior management regarding recent developments and regulatory matters;

viii. participated in certain discussions and negotiations between representatives of ESB and WesBanco;

ix. reviewed the reported prices and trading activity of the equity securities of ESB and WesBanco;

x. analyzed certain publicly available information concerning the terms of selected merger and acquisition transactions that we considered relevant to our analysis;

xi. reviewed and analyzed certain publicly available financial and stock market data relating to selected public companies that we deemed relevant to our analysis;

xii. conducted such other financial studies, analyses and investigations and considered such other information as we deemed necessary or appropriate for purposes of our opinion; and

xiii. took into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience and knowledge of the banking industry generally.

In connection with our review, we have relied upon and assumed, without independent verification, the accuracy and completeness of all of the financial and other information that was provided to Mufson Howe Hunter by or on behalf of ESB or WesBanco, or that was otherwise reviewed by Mufson Howe Hunter, and we have not assumed any responsibility for independently verifying any of such information. We have further relied on the assurances made by ESB or WesBanco that each of them is unaware of any facts that would make their respective information incomplete or misleading. With respect to the financial forecasts supplied to us by ESB and WesBanco (including, without limitation, potential cost savings and operating synergies realized by a potential acquirer), we have assumed that the forecasts were reasonably prepared on the basis reflecting the best currently available estimates and judgments of the management of ESB and WesBanco, as applicable, as to the future operating and financial performance of ESB and WesBanco, as applicable, and that they provided a reasonable basis upon which we could form our Opinion. Such forecasts were not prepared with the expectation of public disclosure. Mufson Howe Hunter has relied on such forecasts without independent verification or analyses and does not in any respect assume any responsibility for the accuracy or completeness thereof.

We assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either ESB or WesBanco since the date of the last financial statements of each company made available to us. We have also assumed, without independent verification and with your consent, that the aggregate allowances for loan losses set forth in the respective financial statements of ESB and WesBanco are, in the aggregate, adequate to cover all such losses. We did not make or obtain any independent evaluation, appraisal or physical inspection of either ESB’s or WesBanco’s assets or liabilities, the collateral securing any of such assets or liabilities, or the collectability of any such assets, nor did we review loan or credit files of ESB or WesBanco. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, Mufson Howe Hunter assumes no responsibility for their accuracy. We relied on advice of ESB’s counsel as to certain legal matters with respect to ESB, the Agreement and the Merger and other matters contained or contemplated therein. In addition, we have assumed, with your consent, that there are no factors that would delay or subject to adverse conditions any necessary regulatory or governmental approval and that all conditions to the Merger will be satisfied and not waived. We have assumed that the Merger will be consummated substantially on the terms and conditions described in the Agreement, without any waiver of material terms and conditions by ESB or any other party, and that obtaining any necessary regulatory approvals

or satisfying any other conditions for consummation of the Merger will not have an adverse effect on ESB or WesBanco. We have assumed that the Merger will be consummated in a matter that complies in all respects with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations.

Our Opinion is necessarily based solely on economic, market, monetary, financial and other conditions as they exist on, and on the information made available to us as of, the date of this letter. It is understood that subsequent developments may affect the conclusions reached in this Opinion and that Mufson Howe Hunter does not have or assume any obligation to update, revise or reaffirm this Opinion. Our Opinion is solely for the information of, and directed to, the ESB Board of Directors (the “Board”) for its information and assistance in connection with its consideration of the financial terms of the Merger and is not to be relied upon by any shareholder of ESB or WesBanco or any other person or entity. Our Opinion does not constitute a recommendation to the Board as to how the Board should vote on the Merger or to any shareholder of ESB or WesBanco as to how any such shareholder should vote at any shareholders’ meeting at which the Merger is considered, or whether or not any ESB shareholder should enter into a voting, shareholders’, or affiliates’ agreement with respect to the Merger. In addition, the Opinion does not compare the relative merits of the Merger with any other alternative transaction or business strategy which may have been available to ESB and does not address the underlying business decision of the Board or ESB to proceed with the Merger or any aspect thereof.

Mufson Howe Hunter, as part of its investment banking services, is regularly engaged in the independent valuation of businesses and securities in connection with mergers, acquisitions, private placements and valuations for corporate and other purposes. We have acted as financial advisor to ESB in connection with the Merger and will receive a fee for our services, a substantial portion of which is contingent upon the completion of the Merger. In addition, ESB has agreed to indemnify us for certain liabilities arising out of our engagement.

Mufson Howe Hunter’s Fairness Opinion Committee has approved the issuance of this opinion. Our Opinion may not be published or otherwise used to refer to, nor shall any public reference to Mufson Howe Hunter be made, without our prior written consent, except in accordance with the terms and conditions of our engagement letter with ESB.

Based upon and subject to the foregoing, we are of the opinion that, as of the date hereof, the Merger Consideration to be received from WesBanco in the Merger pursuant to the Agreement is fair to holders of shares of ESB common stock, from a financial point of view.

Respectfully,

/s/ Mufson Howe Hunter

VOTING AGREEMENT (this “Agreement”), dated as of October 29, 2014, by and between WESBANCO, INC., a West Virginia corporation (“Buyer”), and the undersigned holder (the “Shareholder”) of shares of common stock, $0.01 par value ( the “Seller Shares”), of ESB FINANCIAL CORPORATION, INC., a Pennsylvania corporation (“Seller”).

WHEREAS, concurrently with the execution of this Agreement, Buyer, Wesbanco Bank, Inc., Seller and ESB Bank have entered into an Agreement and Plan of Merger (as such agreement may be subsequently amended or modified, the “Merger Agreement”), providing for, among other things, the merger of Seller with and into Buyer (the “Merger”);

WHEREAS, as of the date of this Agreement, the Shareholder beneficially owns and has sole voting power with respect to the number of Seller Shares, and holds stock options or other rights to acquire the number of Seller Shares, indicated on Schedule 1 attached hereto;

WHEREAS, as used herein, the term “Shares” means all Seller Shares held by the Shareholder on the date of this Agreement and all Seller Shares that the Shareholder purchases, acquires the right to vote or acquires beneficial ownership of (as defined in Rule 13d-3 of the Exchange Act, but excluding Seller Shares underlying unexercised stock options and Seller Shares held by the Shareholder in a fiduciary capacity) prior to the Expiration Date (as defined in Section 2 below), whether by the exercise of any stock options or otherwise;

WHEREAS, it is a condition to the willingness of Buyer to enter into the Merger Agreement that the Shareholder execute and deliver this Agreement; and

WHEREAS, all capitalized terms used in this Agreement without definition herein shall have the meanings ascribed to them in the Merger Agreement.

NOW, THEREFORE, in consideration of the foregoing recitals, the mutual covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Shareholder and Buyer agree as follows:

1. Agreement to Vote Shares. The Shareholder agrees that, prior to the Expiration Date (as defined in Section 2 hereof), at any meeting of the shareholders of Seller, or any adjournment or postponement thereof, or in connection with any written consent of the shareholders of Seller, with respect to the Merger, the Merger Agreement or any Acquisition Proposal, the Shareholder shall:

(a) appear at such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b) vote (or cause to be voted), or execute and deliver a written consent (or cause a written consent to be executed and delivered) covering, all of the Shares that such Shareholder shall be entitled to so vote (i) in favor of adoption and approval of the Merger Agreement and the transactions contemplated thereby, including the Merger, and any action that could reasonably be expected to facilitate the Merger; (ii) against any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty, or any other obligation or agreement, of Seller contained in the Merger Agreement or of the Shareholder contained in this Agreement, or that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect, inhibit or preclude the timely consummation of the Merger or the fulfillment of a condition under the Merger

D-1

Agreement to Seller’s and Buyer’s respective obligations to consummate the Merger or change in any manner the voting rights of any class of shares of Seller (including any amendments to Seller’s articles of incorporation or bylaws); and (iii) against any Acquisition Proposal, or any agreement or transaction that is intended, or could reasonably be expected, to impede, interfere with, delay, postpone, discourage or adversely affect the consummation of the Merger or any of the transactions contemplated by the Merger Agreement.

Any such vote shall be cast or consent shall be given in accordance with such procedures relating thereto so as to ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording the results of such vote or consent.

3. Agreement to Retain Shares; No Voting Trusts.

(a) Until the receipt of the requisite approval of the shareholders of Seller, the Shareholder shall not, except as contemplated by this Agreement or the Merger Agreement, directly or indirectly, sell, assign, transfer, offer, exchange, pledge or otherwise dispose of or encumber (including, without limitation, by the creation of a Lien (as defined in Section 4(c) below) (each, a “Transfer”), or enter into any contract, option, commitment or other arrangement or understanding with respect to, or consent to, any Transfer of, any Shares beneficially owned by the Shareholder or the Shareholder’s voting or economic interest therein. Notwithstanding the foregoing, the Shareholder may make Transfers (a) by will or by operation of law, in which case this Agreement shall bind the transferee, (b) in connection with estate and charitable planning purposes, including Transfers to relatives, trusts and charitable organizations, subject to the transferee’s agreement in writing, in form and substance reasonably satisfactory to Buyer, to be bound by the terms of, and perform the obligations of the Shareholder under, this Agreement, (c) to another shareholder of Seller who previously entered into a Voting Agreement with Buyer and (d) with Buyer’s prior written consent, such consent to be granted or withheld in Buyer’s sole discretion.

(b) The Shareholder agrees that the Shareholder shall not, and shall not permit any entity under the Shareholder’s control to, deposit any of the Shares in a voting trust, grant any proxies with respect to the Shares or subject any of the Shares to any arrangement with respect to the voting of the Shares other than agreements entered into with the Buyer.

4. Representations and Warranties of Shareholder. The Shareholder hereby represents and warrants to Buyer as follows:

(b) this Agreement has been duly and validly executed and delivered by the Shareholder and, assuming this Agreement constitutes a valid and binding agreement of Buyer, is a valid and legally binding agreement of the Shareholder, enforceable against the Shareholder in accordance with its terms (except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar laws of general applicability relating to or affecting creditors’ rights or by general equity principles);

(c) the Shareholder beneficially owns the number of Shares indicated on Schedule 1 (the “Original Shares”), free and clear of any liens, claims, charges or other encumbrances or restrictions of any kind whatsoever (“Liens”);

(d) except pursuant to this Agreement, the Shareholder has sole, and otherwise unrestricted, voting and investment power with respect to the Original Shares, and there are no options, warrants or other rights, agreements, arrangements or commitments of any character to which the Shareholder is a party relating to the pledge, disposition or voting of any of the Original Shares and there are no voting trusts or voting agreements with respect to the Original Shares;

(e) the Shareholder does not beneficially own any Seller Shares other than (i) the Original Shares and (ii) any options, warrants or other rights to acquire any additional shares of Seller Shares or any security exercisable for or convertible into shares of Seller Shares indicated on Schedule 1;

(f) the execution and delivery of this Agreement by the Shareholder does not, and the performance by the Shareholder of his, her or its obligations hereunder and the consummation by the Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a breach of or default (with or without notice or lapse of time or both) under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which the Shareholder is a party or by which the Shareholder is bound, or any statute, rule or regulation to which the Shareholder or the Shareholder’s property or assets is subject or, in the event that the Shareholder is a corporation, partnership, trust or other entity, any bylaw or other organizational document of the Shareholder.

5. No Solicitation. From and after the date hereof until the Expiration Date, the Shareholder, solely in his, her or its capacity as a shareholder of Seller, shall not, nor shall such Shareholder authorize any partner, officer, director, advisor or representative of, such Shareholder or any of his, her or its affiliates to (and, to the extent applicable to the Shareholder, such Shareholder shall use reasonable best efforts to prohibit any of his, her or its representatives or affiliates to), (a) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (b) participate in any discussions or negotiations regarding any Acquisition Proposal, or furnish, or otherwise afford access, to any person (other than Buyer) any information or data with respect to Seller or any Seller Subsidiary or otherwise relating to an Acquisition Proposal, (c) enter into any agreement, agreement in principle or letter of intent with respect to an Acquisition Proposal, (d) solicit proxies or become a “participant” in a “solicitation” (as such terms are defined in Regulation 14A under the Exchange Act) with respect to an Acquisition Proposal (other than the Merger Agreement) or otherwise encourage or assist any party in taking or planning any action that would compete with, restrain or otherwise serve to interfere with or inhibit the timely consummation of the Merger in accordance with the terms of the Merger Agreement, (e) initiate a shareholders’ vote or action by consent of Seller’s shareholders with respect to an Acquisition Proposal, or (f) except by reason of this Agreement, become a member of a “group” (as such term is used in Section 13(d) of the Exchange Act) with respect to any voting securities of Seller that takes any action in support of an Acquisition Proposal.

6. Specific Enforcement. The Shareholder has signed this Agreement intending to be legally bound thereby. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and the Shareholder expressly agrees that this Agreement shall be specifically enforceable in any court of competent jurisdiction in accordance with its terms against the Shareholder, in addition to any other remedy that Buyer may have at law or in equity. All of the covenants and agreements contained in this Agreement shall be binding upon, and inure to the benefit of, the respective parties and their permitted successors, assigns, heirs, executors, administrators and other legal representatives, as the case may be, but, except as otherwise specifically provided herein, neither this Agreement nor any of the rights, interests or obligations of the Shareholder hereunder may be assigned without the prior written consent of Buyer.

7. No Waivers. No waivers of any breach of this Agreement extended by Buyer to the Shareholder shall be construed as a waiver of any rights or remedies of Buyer with respect to any other shareholder of Seller who has executed an agreement substantially in the form of this Agreement with respect to Shares beneficially owned by such shareholder or with respect to any subsequent breach by the Shareholder or any other such shareholder of Seller. No waiver of any provisions hereof by either party shall be deemed a waiver of any other provisions hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

D-3

8. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Buyer any direct or indirect ownership or incidence of ownership of or with respect to any of the Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, and Buyer shall have no authority to direct the Shareholder in the voting or disposition of any of the Shares, except as otherwise provided in this Agreement.

9. Capacity as Shareholder. The Shareholder is signing this Agreement solely in the Shareholder’s capacity as a shareholder of Seller, and not in the Shareholder’s capacity as a director, officer or employee of Seller or any Seller Subsidiary or in the Shareholder’s capacity as a trustee or fiduciary of any employee benefit plan or trust. Notwithstanding anything herein to the contrary, nothing herein shall in any way (a) restrict a director and/or officer of Seller in the exercise of his or her fiduciary duties, consistent with the terms of the Merger Agreement, as a director and/or officer of Seller or in his or her capacity as a trustee or fiduciary of any employee benefit plan or trust, or (b) prevent or be construed to create any obligation on the part of any director and/or officer of Seller or any trustee or fiduciary of any employee benefit plan or trust from taking any action or omitting to take any action in such capacity.

10. Entire Agreement; Amendments. This Agreement supersedes all prior agreements, written or oral, between the parties hereto with respect to the subject matter hereof and contains the entire agreement between the parties with respect to the subject matter hereof. This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto.

11. Further Assurances. From time to time and without additional consideration, the Shareholder shall execute and deliver, or cause to be executed and delivered, such additional transfers, assignments, endorsements, proxies, consents and other instruments, and shall take such further actions, as Buyer may reasonably request for the purpose of carrying out and furthering the purpose and intent of this Agreement.

12. Severability. If any term or other provision of this Agreement is determined to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby are fulfilled to the greatest extent possible.

13. Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed an original but all of which together shall constitute one and the same instrument.

14. Public Disclosure. The Shareholder shall not issue or cause the publication of any press release or other public announcement (to the extent not previously issued or made in accordance with the Merger Agreement) with respect to this Agreement, the Merger Agreement or the transactions contemplated by the Merger Agreement, without the prior consent of Buyer. The Shareholder hereby permits Buyer to publish and disclose in any document and/or schedule filed by Buyer with the SEC and in any press release or other disclosure document the Shareholder’s identity and ownership of Shares and the nature of the Shareholder’s commitments and obligations pursuant to this Agreement.

15. Governing Law; Waiver of Jury Trial.

(a) This Agreement shall be governed by and construed in accordance with the internal laws of the State of West Virginia, without giving effect to the principles of conflicts of laws thereof that would cause the application of the laws of any other jurisdiction.

D-4

(b) EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

16. No Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (a) the Board of Directors of Seller has approved, for purposes of any applicable anti-takeover laws and regulations and any applicable provision of Seller’s articles of incorporation or bylaws, the Merger pursuant to the Merger Agreement, (b) the Merger Agreement is executed by all parties thereto, and (c) this Agreement is executed by all parties hereto.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers.

WesBanco’s Bylaws provide, and West Virginia law permits, the indemnification of directors and officers against certain liabilities. Officers and directors of WesBanco and its subsidiaries are indemnified, to the maximum extent permitted under the West Virginia Business Corporation Act (including advanced indemnification payments), against liabilities incurred in connection with proceedings in which they are made parties by reason of their being or having been directors or officers of the corporation, except for certain prohibitions set forth in WesBanco’s Bylaws regarding “prohibited indemnification payments.” WesBanco does provide indemnity insurance to its officers and directors. Such insurance will not, however, indemnify officers or directors for willful misconduct or gross negligence in the performance of a duty to WesBanco.

I. Article VI of the Bylaws of WesBanco provides:

Indemnification of Directors and Officers

SECTION 1. Indemnification. Each director and officer, whether or not then in office, shall be indemnified by the corporation against liability incurred by and imposed upon him in connection with or resulting from any action, suit or proceeding, to which he may be made a party by reason of his being or having been a director or officer of the corporation, or of any other company which he served at the request of the corporation, to the maximum extent permitted under the West Virginia Business Corporation Act, except as prohibited by Section 2 and Section 4 of this Article VI. The foregoing right of indemnification shall not be exclusive of other rights to which he may be entitled as a matter of law. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding as authorized by the board of directors in accordance with the provisions of the West Virginia Business Corporation Act.

SECTION 2. Prohibited Indemnification Payment. Notwithstanding the provisions of Section 1 of this Article VI, no director or officer shall receive a “prohibited indemnification payment,” which is any payment or agreement to make a payment to pay or reimburse such director or officer for any liability or legal expenses in any administrative proceeding brought by the appropriate federal banking agency that results in a final order or settlement in which the director or officer is assessed a civil money penalty, is removed or prohibited from conducting the business of banking, or is required to cease an action or take any affirmative action, including making restitution, with respect to Wesbanco Bank, Inc. or the corporation.

SECTION 3. Insurance. The corporation may purchase commercial insurance to cover certain costs that the corporation incurs under the indemnification provisions of Section 1 of this Article VI. Costs that may be covered include legal expenses and restitution that an individual may be ordered to make to the corporation. Such insurance may not, however, pay or reimburse a director or officer for any final judgment or civil money penalty assessed against such individual. Furthermore, partial indemnification for legal expenses is permitted in connection with a settlement when there is a formal and final finding that the director or officer has not breached a fiduciary duty, engaged in unsafe or unsound practices, and is not subject to a final prohibition order.

SECTION 4. Determination that Indemnification is Proper. The corporation may make or agree to make a reasonable indemnification payment if all of the following conditions are met: (i) the board of directors investigates and determines in writing that the director or officer acted in good faith and in the best interests of Wesbanco Bank, Inc.; (ii) the board of directors investigates and determines that the payment will not materially adversely affect the safety and soundness of Wesbanco Bank, Inc. or the corporation; (iii) the payment does not fall within the definition of a prohibited indemnification payment; and (iv) the director or officer agrees in writing to reimburse the corporation, to the extent not covered by permissible insurance, for advanced indemnification payments that subsequently become prohibited indemnification payments.

II-1

II. W. Va. Code Section 31D-8-851 through Section 31D-8-856 provides:

Section 31D-8-851. Permissible Indemnification.

(a) Except as otherwise provided in this section, a corporation may indemnify an individual who is a party to a proceeding because he or she is a director against liability incurred in the proceeding if:

(1) (A) He or she conducted himself or herself in good faith; and

(B) He or she reasonably believed: (i) In the case of conduct in his or her official capacity, that his or her conduct was in the best interests of the corporation; and (ii) in all other cases, that his or her conduct was at least not opposed to the best interests of the corporation; and

(C) In the case of any criminal proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful; or

(2) He or she engaged in conduct for which broader indemnification has been made permissible or obligatory under a provision of the articles of incorporation as authorized by subdivision (5), subsection (b), section two hundred two, article two of this chapter.

(c) The termination of a proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, is not determinative that the director did not meet the relevant standard of conduct described in this section.

(d) Unless ordered by a court under subdivision (3), subsection (a), section eight hundred fifty-four of this article, a corporation may not indemnify a director:

(1) In connection with a proceeding by or in the right of the corporation, except for reasonable expenses incurred in connection with the proceeding if it is determined that the director has met the relevant standard of conduct under subsection (a) of this section; or

(2) In connection with any proceeding with respect to conduct for which he or she was adjudged liable on the basis that he or she received a financial benefit to which he or she was not entitled, whether or not involving action in his or her official capacity.

Section 31D-8-852. Mandatory Indemnification.

A corporation must indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he or she was a party because he or she was a director of the corporation against reasonable expenses incurred by him or her in connection with the proceeding.

Section 31D-8-853. Advance for Expenses.

(a) A corporation may, before final disposition of a proceeding, advance funds to pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding because he or she is a director if he or she delivers to the corporation:

(1) A written affirmation of his or her good faith belief that he or she has met the relevant standard of conduct described in section eight hundred fifty-one of this article or that the proceeding involves conduct for which liability has been eliminated under a provision of the articles of incorporation as authorized by subdivision (4), subsection (b), section two hundred two, article two of this chapter; and

II-2

(2) His or her written undertaking to repay any funds advanced if he or she is not entitled to mandatory indemnification under section eight hundred fifty-two of this article and it is ultimately determined under section eight hundred fifty-four or eight hundred fifty-five of this article that he or she has not met the relevant standard of conduct described in section eight hundred fifty-one of this article.

(b) The undertaking required by subdivision (2), subsection (a) of this section must be an unlimited general obligation of the director but need not be secured and may be accepted without reference to the financial ability of the director to make repayment.

(c) Authorizations under this section are to be made:

(1) By the board of directors:

(A) If there are two or more disinterested directors, by a majority vote of all the disinterested directors, a majority of whom constitute a quorum for this purpose, or by a majority of the members of a committee of two or more disinterested directors appointed by a vote; or

(B) If there are fewer than two disinterested directors, by the vote necessary for action by the board in accordance with subsection (c), section eight hundred twenty-four of this article in which authorization directors who do not qualify as disinterested directors may participate; or

(3) By special legal counsel selected in a manner in accordance with subdivision (2), subsection (b), section eight hundred fifty-five of this article.

Section 31D-8-854. Circuit Court-Ordered Indemnification and Advance for Expenses.

After receipt of an application and after giving any notice it considers necessary, the circuit court shall:

(1) Order indemnification if the circuit court determines that the director is entitled to mandatory indemnification under section eight hundred fifty-two of this article;

(2) Order indemnification or advance for expenses if the circuit court determines that the director is entitled to indemnification or advance for expenses pursuant to a provision authorized by subsection (a), section eight hundred fifty-eight of this article; or

(3) Order indemnification or advance for expenses if the circuit court determines, in view of all the relevant circumstances, that it is fair and reasonable:

(A) To indemnify the director; or

(B) To advance expenses to the director, even if he or she has not met the relevant standard of conduct set forth in subsection (a), section eight hundred fifty-one of this article, failed to comply with section eight hundred fifty-three of this article or was adjudged liable in a proceeding referred to in subdivision (1) or (2), subsection (d), section eight hundred fifty-one of this article, but if he or she was adjudged so liable his or her indemnification is to be limited to reasonable expenses incurred in connection with the proceeding.

(b) If the circuit court determines that the director is entitled to indemnification under subdivision (1), subsection (a) of this section or to indemnification or advance for expenses under subdivision (2) of said

II-3

subsection, it shall also order the corporation to pay the director’s reasonable expenses incurred in connection with obtaining circuit court-ordered indemnification or advance for expenses. If the circuit court determines that the director is entitled to indemnification or advance for expenses under subdivision (3) of said subsection, it may also order the corporation to pay the director’s reasonable expenses to obtain circuit court-ordered indemnification or advance for expenses.

Section 31D-8-855. Determination and Authorization of Indemnification.

(a) A corporation may not indemnify a director under section eight hundred fifty-one of this article unless authorized for a specific proceeding after a determination has been made that indemnification of the director is permissible because he or she has met the relevant standard of conduct set forth in section eight hundred fifty-one of this article.

(b) The determination is to be made:

(1) If there are two or more disinterested directors, by the board of directors by a majority vote of all the disinterested directors, a majority of whom constitute a quorum for this purpose, or by a majority of the members of a committee of two or more disinterested directors appointed by a vote;

(2) By special legal counsel:

(A) Selected in the manner prescribed in subdivision (1) of this subsection; or

(B) If there are fewer than two disinterested directors, selected by the board of directors in which selection directors who do not qualify as disinterested directors may participate; or

(3) By the shareholders, but shares owned by or voted under the control of a director who at the time does not qualify as a disinterested director may not be voted on the determination.

(c) Authorization of indemnification is to be made in the same manner as the determination that indemnification is permissible, except that if there are fewer than two disinterested directors or if the determination is made by special legal counsel, authorization of indemnification is to be made by those entitled under paragraph (B), subdivision (2), subsection (b) of this section to select special legal counsel.

Section 31D-8-856. Indemnification of Officers.

(a) A corporation may indemnify and advance expenses under this part to an officer of the corporation who is a party to a proceeding because he or she is an officer of the corporation:

(1)To the same extent as a director; and

(2) If he or she is an officer but not a director, to a further extent as may be provided by the articles of incorporation, the bylaws, a resolution of the board of directors or contract except for:

(A) Liability in connection with a proceeding by or in the right of the corporation other than for reasonable expenses incurred in connection with the proceeding; or

(B) Liability arising out of conduct that constitutes:

(i) Receipt by him or her of a financial benefit to which he or she is not entitled;

(ii) An intentional infliction of harm on the corporation or the shareholders; or

(iii) An intentional violation of criminal law.

(b) The provisions of subdivision (2), subsection (a) of this section apply to an officer who is also a director if the basis on which he or she is made a party to the proceeding is an act or omission solely as an officer.

II-4

(c) An officer of a corporation who is not a director is entitled to mandatory indemnification under section eight hundred fifty-two of this article and may apply to a court under section eight hundred fifty-four of this article for indemnification or an advance for expenses in each case to the same extent to which a director may be entitled to indemnification or advance for expenses under those provisions.

Certain rules of the Federal Deposit Insurance Corporation limit the ability of certain depository institutions, their subsidiaries and their affiliated depository institution holding companies to indemnify affiliated parties, including institution directors. In general, subject to the ability to purchase directors’ and officers’ liability insurance and to advance professional expenses under certain circumstances, the rules prohibit such institutions from indemnifying a director for certain costs incurred with regard to an administrative or enforcement action commenced by any federal banking agency that results in a final order or settlement pursuant to which the director is assessed a civil money penalty, removed from office, prohibited from participating in the affairs of an insured depository institution or required to cease and desist from or take an affirmative action described in Section 8(b) of the Federal Deposit Insurance Act (12 U.S.C. § 1818(b)).

Item 22. Undertakings.

The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) that, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(5) that, for purposes of determining any liability under the Securities Act of 1933, each filing of the undersigned’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of any employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-6

(6) that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(7) that every prospectus: (i) that is filed pursuant to paragraph (6) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(8) to respond to requests for information that is incorporated by reference into this prospectus pursuant to Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(9) for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(10) to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(11) to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Wheeling, West Virginia 26003

Ladies and Gentlemen:

We have acted as counsel for Wesbanco, Inc., a West Virginia corporation (“WesBanco”), in connection with the Registration Statement on Form S-4 (the “Registration Statement”) filed with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the “Act”), for the registration of shares of common stock, par value $2.0833 per share, of WesBanco (the “Shares”), that may be issued in connection with the merger of ESB Financial Corporation, a Pennsylvania corporation (“ESB”), with and into WesBanco as described in the Registration Statement.

We have participated in the preparation of the Registration Statement and have reviewed the Agreement and Plan of Merger, dated as of October 29, 2014, by and between Wesbanco, Wesbanco Bank, Inc., a West Virginia banking corporation and a wholly owned subsidiary of WesBanco, ESB and ESB Bank, a Pennsylvania state-chartered bank and a wholly owned subsidiary of ESB (the “Merger Agreement”). We have also reviewed originals or copies, certified or otherwise identified to our satisfaction, of all such corporate records of WesBanco and such other instruments and certificates of public officials, officers and representatives of WesBanco and such other persons, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinion expressed below.

In rendering this opinion expressed below, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies and the authenticity of the originals of such copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on and subject to the foregoing, we are of the opinion that the Shares have been duly authorized for issuance by WesBanco and, when the Registration Statement has become effective under the Act, the articles of merger have been duly filed with the Secretary of State of the State of West Virginia and the Department of State of the Commonwealth of Pennsylvania, and the Shares have been duly issued in accordance with the Merger Agreement, the Shares will be validly issued, fully paid, and nonassessable.

The foregoing opinion is limited to the federal law of the United States of America and the West Virginia Business Corporation Act (including the applicable reported judicial decisions interpreting that law).

We assume no obligation to update or supplement the foregoing opinion in order to reflect any changes of law or fact that may occur.

We hereby consent to the filing of this opinion with the Securities and Exchange Commission as an exhibit to the Registration Statement, and to the references therein to our firm and this opinion under the caption “Legal Matters” in the proxy statement/prospectus constituting a part of the Registration Statement. In giving such consent, we do not admit that we come within the category of persons whose consent is required under Section 7 of the Act.

Yours very truly,

Re: Agreement and Plan of Merger dated as of October 29, 2014 (the “Merger Agreement”) by and among WesBanco, Inc., a West Virginia corporation (“WesBanco”), WesBanco Bank, Inc., a West Virginia banking corporation and a wholly-owned subsidiary of WesBanco, ESB Financial Corporation, a Pennsylvania corporation and savings and loan holding company (“ESB”), and ESB Bank, a Pennsylvania state-chartered stock savings bank and a wholly-owned subsidiary of ESB.

Ladies and Gentlemen:

We have acted as special counsel for WesBanco in connection with the Merger Agreement pursuant to which (i) ESB will merge with and into WesBanco (the “Merger”) with WesBanco being the surviving corporation and (ii) ESB Bank will merge with and into WesBanco Bank, Inc. (the “Bank Merger” and together with the Merger, the “Mergers”), with WesBanco Bank Inc. being the surviving institution, on the terms and conditions set forth therein. For purposes of this opinion, capitalized terms used and not otherwise defined herein shall have the meaning ascribed thereto in the Merger Agreement and references herein to the Merger Agreement shall include all exhibits and schedules thereto.

We have examined (i) the Merger Agreement, (ii) the Registration Statement on Form S-4 (the “Registration Statement,” which reference shall include the proxy statement/prospectus of WesBanco and ESB included therein) being filed by WesBanco with the Securities and Exchange Commission (the “SEC”), and (iii) the representation letters of WesBanco and ESB delivered to us for purposes of this opinion (the “Representation Letters”). In addition, we have examined and relied as to matters of fact upon originals or copies, certified or otherwise identified to our satisfaction, of such corporate records, agreements, documents and other instruments and made such other inquiries as we have deemed necessary or appropriate to enable us to render the opinion set forth below. In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents

Board of Directors

WesBanco, Inc.

November 20, 2014

Page 2

submitted to us as duplicates or certified or conformed copies, and the authenticity of the originals of such latter documents. We have not, however, undertaken any independent investigation of any factual matter set forth in any of the foregoing.

In rendering such opinion, we have assumed that (i) each of the Mergers will be effected in accordance with the Merger Agreement and as described in the Registration Statement, including satisfaction of all material covenants and conditions to the obligations of the parties without amendment or waiver thereof, (ii) the relevant statements concerning the Mergers set forth in the Merger Agreement and the Registration Statement are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, (iii) the representations made by WesBanco and ESB in their respective Representation Letters are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, and (iv) any representations made in the Merger Agreement, if relevant, or the Representation Letters “to the best knowledge of,” or based on the belief of WesBanco or ESB or similarly qualified, are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, in each case without such qualification. We have also assumed that the parties have complied with, and, if applicable, will continue to comply with, the relevant covenants contained in the Merger Agreement, including an assumption that none of the parties will take any action after the Effective Time that would cause the Mergers not to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). If any of the above assumptions are untrue for any reason, our opinion might be adversely affected and may not be relied upon.

Based upon and subject to the foregoing, including without limitation the qualifications, exceptions and assumptions set forth herein and in the Registration Statement, it is our opinion that for U.S. federal income tax purposes:

(i) Each of the Mergers will constitute a reorganization within the meaning of Section 368(a) of the Code;

(ii) Each of WesBanco and ESB will be a party to the reorganization within the meaning of Section 368(b) of the Code;

(iii) Each of WesBanco Bank, Inc. and ESB Bank will be a party to the reorganization within the meaning of Section 368(b) of the Code; and

(iv) The descriptions of the law and the legal conclusions contained under the caption “Material U.S. Federal Income Tax Consequences of the Merger” in the Registration Statement as they relate to the United States federal income tax are correct in all material respects.

We express our opinion herein only as to those matters specifically set forth above, no opinion should be inferred as to the tax consequences of the Mergers under any state, local or foreign laws or with respect to other areas of United States federal taxation, and we do not express any opinion herein

Board of Directors

WesBanco, Inc.

November 20, 2014

Page 3

concerning any law other than the federal law of the United States. In addition, we express no opinion as to the tax treatment of any conditions existing at the time of, or effects resulting from, transactions which are not specifically addressed herein. We express no opinion as to whether the discussion contained in the Registration Statement under the caption “Material U.S. Federal Income Tax Consequences of the Merger” addresses all of the United States federal income tax consequences of the Mergers that may be applicable to WesBanco.

Our opinion represents our legal judgment as to the described federal income tax consequences of the Mergers. Our opinion is based on current statutory, regulatory and judicial authority, any of which might be changed at any time with retroactive effect, and our knowledge of the facts as of the date hereof.

Re: Agreement and Plan of Merger dated as of October 29, 2014 (the “Merger Agreement”) by and among WesBanco, Inc., a West Virginia corporation (“WesBanco”), WesBanco Bank, Inc., a West Virginia banking corporation and a wholly-owned subsidiary of WesBanco, ESB Financial Corporation, a Pennsylvania corporation and savings and loan holding company (“ESB”), and ESB Bank, a Pennsylvania state-chartered stock savings bank and a wholly-owned subsidiary of ESB

Ladies and Gentlemen:

We have acted as special counsel for ESB in connection with the Merger Agreement pursuant to which (i) ESB will merge with and into WesBanco (the “Merger”) with WesBanco being the surviving corporation, and (ii) ESB Bank will merge with and into WesBanco Bank, Inc. (the “Bank Merger” and together with the Merger, the “Mergers”), with WesBanco Bank, Inc. being the surviving institution, on the terms and conditions set forth therein. For purposes of this opinion, capitalized terms used and not otherwise defined herein shall have the meaning ascribed thereto in the Merger Agreement, and references herein to the Merger Agreement shall include all exhibits and schedules thereto.

We have examined (i) the Merger Agreement, (ii) the Registration Statement on Form S-4 (the “Registration Statement,” which reference shall include the proxy statement/prospectus of WesBanco and ESB included therein) being filed by WesBanco with the Securities and Exchange Commission (the “SEC”), and (iii) the representation letters of WesBanco and ESB delivered to us for purposes of this opinion (the “Representation Letters”). In addition, we have examined and relied as to matters of fact upon originals or copies, certified or otherwise identified to our satisfaction, of such corporate records, agreements, documents and other instruments and made such other inquiries as we have deemed necessary or appropriate to enable us to render the opinion set forth below. In such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to

Board of Directors

us as duplicates or certified or conformed copies, and the authenticity of the originals of such latter documents. We have not, however, undertaken any independent investigation of any factual matter set forth in any of the foregoing.

In rendering such opinion, we have assumed that (i) each of the Mergers will be effected in accordance with the Merger Agreement and as described in the Registration Statement, including satisfaction of all material covenants and conditions to the obligations of the parties without amendment or waiver thereof, (ii) the relevant statements concerning the Mergers set forth in the Merger Agreement and the Registration Statement are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, (iii) the representations made by WesBanco and ESB in their respective Representation Letters are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, and (iv) any representations made in the Merger Agreement, if relevant, or the Representation Letters “to the best knowledge of,” or based on the belief of WesBanco or ESB or similarly qualified, are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, in each case without such qualification. We have also assumed that the parties have complied with, and, if applicable, will continue to comply with, the relevant covenants contained in the Merger Agreement, including an assumption that none of the parties will take any action after the Effective Time that would cause the Mergers not to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”). If any of the above assumption are untrue for any reason, our opinion might be adversely affected and may not be relied upon.

Based upon and subject to the foregoing, including without limitation the qualifications, exceptions and assumptions set forth herein and in the Registration Statement, it is our opinion that for U.S. federal income tax purposes:

(i) Each of the Mergers will constitute a reorganization within the meaning of Section 368(a) of the Code;

(ii) Each of WesBanco and ESB will be a party to the reorganization within the meaning of Section 368(b) of the Code;

(iii) Each of WesBanco Bank, Inc. and ESB Bank will be a party to the reorganization within the meaning of Section 368(b) of the Code; and

(iv) The descriptions of the law and the legal conclusions contained under the caption “Material U.S. Federal Income Tax Consequences of the Merger” in the Registration Statement as they relate to the United States federal income tax are correct in all material respects.

We express our opinion herein only as to those matters specifically set forth above, no opinion should be inferred as to the tax consequences of the Mergers under any state, local or

foreign laws or with respect to other areas of United States federal taxation, and we do not express any opinion herein concerning any law other than the federal law of the United States. In addition, we express no opinion as to the tax treatment of any conditions existing at the time of, or effects resulting from, transactions which are not specifically addressed herein. We express no opinion as to whether the discussion contained in the Registration Statement under the caption “Material U.S. Federal Income Tax Consequences of the Merger” addresses all of the United States federal income tax consequences of the Mergers that may be applicable to ESB or the holders of ESB common stock.

Our opinion represents our legal judgment as to the described federal income tax consequences of the Mergers. Our opinion is based on current statutory, regulatory and judicial authority, any of which might be changed at any time with retroactive effect, and our knowledge of the facts as of the date hereof. If (i) the relevant facts at the time of closing differ from those represented to us in the Representation Letters or reflected in the Registration Statement, (ii) the Mergers are completed under terms not contained in the Merger Agreement, (iii) our assumptions prove to be untrue, or (iv) the existing authorities are modified by legislative, administrative or judicial action, our conclusions may differ and our opinion may not be relied upon. In such event, we disclaim any undertaking to advise you of any subsequent changes of the matters stated, represented or assumed herein or any subsequent changes in applicable law, regulations or interpretations thereof.

You should be aware that no ruling has been sought or obtained from the Internal Revenue Service (the “Service”) as to the federal income tax consequences of any aspect of the Mergers and that our opinion is not binding on the Service. You should also be aware that there can be no assurance, and none is hereby given, that the Service will not take a position contrary to the position reflected in our opinion, or that our opinion will be upheld by the courts if challenged by the Service.

As described in the enclosed materials, your proxy as a shareholder of ESB Financial Corporation is being solicited in connection with our upcoming Special Meeting of Shareholders because you have shares of ESB common stock allocated to your account under the Employee Stock Ownership Plan (“ESOP”) or the Retirement Savings Plan (“401(k) Plan”). I hope you will take advantage of the opportunity to direct the manner in which shares of ESB common stock allocated to your accounts under these plans will be voted at the Special Meeting. At the Special Meeting, shareholders will be asked to approve an Agreement and Plan of Merger pursuant to which ESB Financial Corporation will be merged with and into WesBanco, Inc.

Enclosed with this letter is a Joint Proxy Statement/Prospectus, which describes the Merger Agreement and related matters to be voted upon at the Special Meeting, along with a voting instruction ballot, which will permit you to vote the shares allocated to your account(s) in the plans. After you have reviewed the Joint Proxy Statement/Prospectus, we urge you to vote your shares held pursuant to the plans by marking, dating, signing and returning the enclosed voting instruction ballot(s) to the administrators of the plans, who will tabulate the votes for the Trustees of the plans. The Trustees will certify the totals to ESB for the purpose of having those shares voted at the Special Meeting.

We urge each of you to vote, as a means of participating in the governance of the affairs of ESB. If your voting instructions for the ESOP are not received, the shares allocated to your account will be voted by the Trustees in the same ratio as to those shares for which participants’ instructions are received. If your voting instructions for the 401(k) Plan are not received, the shares allocated to your account will not be voted. While I hope that you will vote in the manner recommended by the board of directors, the most important thing is that you vote in whatever manner you deem appropriate. Please take a moment to do so.
